Remote code execution in the submariner-operator component of Red Hat Advanced Cluster Management for Kubernetes 2.x allows a cluster administrator-or any user holding RBAC permissions to modify the Submariner Custom Resource-to reference an unvalidated, attacker-controlled container image path, causing the operator to deploy and execute arbitrary code with elevated privileges across the entire cluster, including control-plane nodes. The root cause (CWE-20: Improper Input Validation) is the absence of image path sanitization or verification before the operator acts on the Submariner CR field, enabling privilege escalation beyond the user's intended cluster boundary. No public exploit code and no CISA KEV listing have been identified at time of analysis, but the Changed Scope with full C:H/I:H/A:H impact ratings signal potential for complete cluster compromise once the high-privilege prerequisite is met.
Cleartext storage of a long-lived broker service account bearer token in the Submariner Custom Resource specification exposes full mesh network control to any Kubernetes principal with CR read access. Red Hat Advanced Cluster Management for Kubernetes 2 (RHACM 2) is confirmed affected via CPE. An attacker who retrieves the token - through a routine `kubectl get` invocation or direct etcd access - gains unrestricted authority to manage Submariner endpoints, secrets, and cross-cluster network resources, constituting a complete compromise of the multi-cluster network plane. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Cleartext storage of the IPsec pre-shared key (PSK) in the Submariner Custom Resource exposes the cryptographic secret used to secure all inter-cluster communication in Red Hat Advanced Cluster Management for Kubernetes 2 deployments. Any principal with low-privilege read access to the Submariner CR object within the Kubernetes cluster can retrieve the PSK and use it to passively decrypt IPsec-encrypted traffic flowing between every cluster in the connected mesh - not just the cluster where access was obtained (CVSS scope change S:C). No public exploit code exists and the vulnerability is not listed in CISA KEV, but the architectural impact is severe: a single stolen key compromises the confidentiality of all inter-cluster traffic simultaneously.
Credential exposure in Red Hat Advanced Cluster Management for Kubernetes 2.x allows any local user with access to a must-gather diagnostic archive to read proxy basic-auth credentials in plaintext. The must-gather component dumps the cluster Proxy object in raw form, bypassing the redaction logic that oc inspect would normally apply to sanitize sensitive fields before archiving. No public exploit code exists and this is not listed in CISA KEV, but the CVSS AV:L/PR:L vector confirms real-world exposure is bounded to archive access rather than remote exploitation.
Cleartext credential exposure in Red Hat Advanced Cluster Management for Kubernetes affects the must-gather diagnostic tool, which collects ACM wrapper Custom Resources containing embedded Secret data without scrubbing sensitive fields. Any administrator who runs must-gather to diagnose cluster issues inadvertently captures credentials and tokens in the resulting archive, which may then be stored, shared, or transmitted without awareness of the embedded secrets. No public exploit identified at time of analysis, but the information disclosure risk is compounded by the routine, trust-assumed nature of diagnostic archive handling.
Out-of-bounds memory read in BlueZ's AVRCP implementation allows a physically proximate attacker - within Bluetooth radio range - to crash the bluetoothd daemon and potentially leak heap memory contents by sending a malformed GetFolderItems response. The flaw resides in parse_media_element() and parse_media_folder(), which fail to validate packet length fields before reading. Exploitation requires the victim to interactively pair with the attacker-controlled malicious Bluetooth device. No public exploit code or CISA KEV listing has been identified at time of analysis.
Red Hat Quay's notification API exposes sensitive integration secrets - including webhook URLs, Slack tokens, and email addresses - to any authenticated repository administrator who can enumerate or guess a target notification's UUID. The flaw is an Insecure Direct Object Reference (CWE-639): the notification UUID acts as the sole access control key, with no ownership check verifying that the requesting admin belongs to the repository whose notification is being accessed. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, but the confidentiality impact is High per CVSS due to the sensitivity of the exposed secrets.
LDAP injection in Red Hat Quay 3's external LDAP authentication handler allows unauthenticated network attackers to inject filter metacharacters into LDAP queries when the directory server returns a referral response. Exploitation enables user-existence oracle attacks against the referral Directory Name and can potentially influence which Distinguished Name is used during password binding in multi-domain Active Directory environments. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog; however, the network-accessible attack vector and lack of authentication requirement elevate practical concern for organizations using LDAP-integrated Quay deployments.
JWT claim validation failures in Red Hat Quay's federated robot account and SSO authentication pathways allow an attacker who already holds a legitimately-issued token from the same configured identity provider to bypass audience (`aud`), authorized party (`azp`), and subject (`sub`) restrictions. Affected deployments include Red Hat Quay 3 and Red Hat OpenShift Update Service across all currently tracked versions. Successful exploitation yields unauthorized access to registry resources beyond the attacker's intended scope, including potential cross-account or cross-namespace read and write access within the Quay instance. No public exploit code has been identified and this CVE is not currently listed in the CISA KEV catalog.
Denial of service in dnsmasq's DNSSEC validation code allows an attacker who operates any DNSSEC-signed authoritative zone to permanently hang the dnsmasq process with a single crafted DNS response, killing all DNS resolution for every client served by that instance. Affected deployments include dnsmasq as packaged in Red Hat Enterprise Linux 6 through 10 and Red Hat OpenShift Container Platform 4. No public exploit code or active exploitation has been identified at time of analysis; the assigned CVSS score of 4.4 (Medium) carries a notable inconsistency between the stated local attack vector and the network-delivered attack mechanism described.
Undertow's HTTP response header writing path silently truncates 16-bit Unicode characters to 8-bit bytes via a narrowing cast in the `writeString()` method, enabling remote unauthenticated attackers to inject ASCII control characters or special symbols into response headers when an application passes unsanitized user-controlled input into those headers. Affected Red Hat distributions include RHEL 8/9/10, JBoss EAP 7, Red Hat Build of Apache Camel for Spring Boot 4, and Red Hat Single Sign-On 7, as reported by Red Hat via Bugzilla #2516038. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Privileged file corruption and denial of service in sblim-sfcb (Small Footprint CIM Broker) on Red Hat Enterprise Linux 6 through 10 is achievable by a local low-privileged attacker exploiting a symlink-based race condition during privileged instance migration. The SFCB daemon writes to a temporary file in /tmp without atomic safety guarantees, allowing an attacker who repeatedly races a symbolic link into place to redirect that privileged write to an arbitrary file path. No public exploit has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
Out-of-bounds memory read in sblim-sfcb's provider-manager IPC message parser allows a local low-privileged attacker to crash the provider-manager process, causing denial of service and potentially leaking limited adjacent memory contents. The vulnerability stems from unsafe deserialization of attacker-controlled IPC messages without adequate boundary validation, affecting sblim-sfcb as shipped across Red Hat Enterprise Linux versions 6 through 10. No public exploit code or active exploitation has been identified at time of analysis, and exploitation is constrained to local system access.
Insecure temporary file creation in sblim-cmpi-base provider registration scripts exposes Red Hat Enterprise Linux 6 through 10 to a local symlink attack, enabling a low-privileged user to redirect privileged file writes to arbitrary paths. When registration scripts execute under elevated (root) privileges, an attacker who pre-positions a symlink in a world-writable directory can cause those scripts to overwrite root-owned files, disrupting system services or integrity. No public exploit code has been identified at time of analysis, and exploitation requires both local access and favorable timing, but the integrity and availability impact on a compromised host are rated high by the vendor.
The iscsiuio DHCP parser in open-iscsi crashes when processing maliciously crafted DHCP reply packets, disrupting iSCSI storage connectivity or network boot on affected hosts. An integer underflow (CWE-191) in the IPv4/UDP DHCP reply parsing path triggers an out-of-bounds read, causing the iscsiuio process to terminate; impact is limited to availability with no confidentiality or integrity exposure. No public exploit code or active exploitation has been identified at time of analysis, and the adjacent-network attack vector constrains the realistic attacker population to the same Layer-2 segment as the target.
Excessive Kubernetes RBAC privileges in the insights-client ServiceAccount within Red Hat Advanced Cluster Management for Kubernetes 2 expose all cluster Secrets to any attacker who compromises the pod or obtains its token. The ServiceAccount is bound to a ClusterRole granting cluster-wide get, list, and watch on all Secrets, far exceeding the single Secret the component actually requires. If the insights-client pod is breached, an attacker can read every Secret across the hub cluster - including managed-cluster kubeconfigs - enabling lateral movement to downstream managed clusters. No public exploit code has been identified at time of analysis, and this CVE is not listed in CISA KEV.
Integer underflow in open-iscsi's iscsiuio daemon crashes the process when parsing malformed DHCPv6 Advertise packets with a truncated UDP length field, disrupting iSCSI storage connectivity. Systems running Red Hat Enterprise Linux 9 and 10 with iscsiuio actively engaged in a DHCPv6 exchange are exploitable by any unauthenticated attacker on the same adjacent network segment. No active exploitation (CISA KEV) or public proof-of-concept has been identified at time of analysis; real-world impact is highest in shared or multi-tenant storage network environments where adjacency cannot be guaranteed.
Denial of service in open-iscsi's iscsiuio daemon allows an unauthenticated attacker on the same local network segment to render the daemon permanently unresponsive by sending a single crafted ICMPv6 Router Advertisement carrying a zero-length option, triggering an infinite loop and sustained CPU exhaustion. Affected deployments include Red Hat Enterprise Linux 9 and 10 systems where iscsiuio is active for iSCSI hardware offload. A secondary out-of-bounds read risk exists when a short IPv6 payload is processed, though no memory corruption or data exposure has been confirmed from available intelligence; no public exploit code or CISA KEV listing has been identified at time of analysis.
Credential interception in Red Hat Multicluster Engine for Kubernetes (MCE) exposes newly rotated provider credentials through an authorization bypass in the provider-credential-controller component. An attacker with specific hub cluster permissions and prior knowledge of a credential value can manipulate `copiedFrom` labels to hijack the credential rotation process, gaining unauthorized read access to sensitive credentials scoped across managed clusters. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but the high confidentiality impact and cross-cluster scope change make this a meaningful risk in mixed-trust MCE deployments.
Integer underflow in GStreamer's avidemux element allows a remote unauthenticated attacker to trigger heap out-of-bounds read and write, heap memory disclosure, and application crash by delivering a crafted AVI file containing a malformed FUJIFILM strd chunk. The gst_avi_demux_parse_strd() function decrements its remaining-length counter by fixed offsets without bounds checking, causing unsigned integer wraparound for payloads of exactly 106 or 107 bytes. Because avidemux is auto-plugged by GStreamer's high-level components (playbin, decodebin, gst-discoverer), any application that opens or previews a media file - including GNOME Files, Nautilus, Totem, and many others - can trigger the vulnerability without user awareness. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis; a vendor-released patch is available in gst-plugins-good 1.28.6.
Out-of-bounds read in GStreamer's avidemux plugin (gst-plugins-good) allows a remote, unauthenticated attacker to crash media-processing applications and potentially leak memory contents by supplying a crafted AVI file. The flaw resides in gst_avi_demux_riff_parse_vprp(), where the count of video field descriptors is derived by dividing remaining buffer size by an attacker-controlled vprp->fields value rather than the struct size, causing the parser to treat more descriptors as valid than the buffer holds. User interaction is required to trigger the bug (the victim must open or stream the malicious AVI via playbin or decodebin), and the primary confirmed impact is denial of service; limited information disclosure is also possible. No public exploit or CISA KEV listing has been identified at time of analysis.
Use-After-Free vulnerabilities in the GNU linker (ld) component of binutils crash the linker process when processing crafted object or archive files during LTO-enabled linking on Red Hat Enterprise Linux systems. The flaws exist at three distinct dereference points in add_archive_element() in ld/ldmain.c, where plugin_maybe_claim() frees the BFD object but the caller retains dangling pointers that are subsequently accessed. The attack surface is confined to build-time environments, with the primary realistic threat being a supply chain attack introducing a malicious object file into CI/CD pipelines or developer build systems; no public exploit code or active exploitation has been confirmed at time of analysis.
Heap corruption via double-free in 389-ds-base's LDAP control parsing allows an unauthenticated remote attacker to crash the directory service with a single crafted BIND request. The flaw resides in `get_ldapmessage_controls_ext()`, which frees a parsed controls array when rejecting an unknown critical Session Tracking control but fails to clear the corresponding SLAPI_REQCONTROLS pblock slot - causing operation teardown to free the same pointer a second time. Affected deployments include Red Hat Directory Server 11 through 13 and the 389-ds-base package across all supported RHEL versions (6-10). No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog; the CVSS AC:H rating reflects that reliable heap exploitation requires specific memory layout conditions rather than a trivially repeatable one-shot crash.
Cross-namespace Secret manipulation in the multicloud-operators-channel component of Red Hat Advanced Cluster Management for Kubernetes 2 (RHACM) enables an authenticated low-privileged user holding specific channel-related permissions to read or modify Kubernetes Secrets outside their authorized namespace scope. The CVSS S:C (Changed Scope) metric confirms the flaw crosses namespace trust boundaries - a critical boundary in multi-tenant Kubernetes environments - potentially exposing credentials, service account tokens, or application secrets belonging to other tenants, and enabling privilege escalation. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Open redirect in the oauth-server component of Red Hat OpenShift Container Platform 4 allows a remote attacker to craft a malicious OAuth grant URL that, upon interaction by an authenticated user, silently redirects that user to an attacker-controlled site. The root cause is the absence of server-side validation on the 'then' parameter in the grant approval handler (CWE-601), making every OpenShift OAuth endpoint a potential phishing launcher. No public exploit code or CISA KEV listing has been identified at time of analysis; the CVSS 4.3 Medium score reflects the required user interaction as the primary limiting factor.
HTTP request smuggling in Undertow's ChunkReader component enables unauthenticated remote attackers to inject out-of-sync requests, bypassing upstream security controls such as authentication layers or reverse-proxy ACLs. Affected deployments include JBoss EAP 7, WildFly, Red Hat Enterprise Linux 8/9/10, Red Hat Data Grid 8, Red Hat Fuse 7, Red Hat Single Sign-On 7, and several Apache Camel-based Red Hat products. No confirmed active exploitation or public proof-of-concept has been identified at time of analysis; the CVSS 5.3 Medium score reflects limited direct impact, though real-world risk in proxy-fronted architectures is meaningfully higher than the score alone suggests.
Cleartext credential exposure in Red Hat insights-core allows SSSD LDAP bind passwords (ldap_default_authtok) and Pacemaker fence device credentials to be included unredacted in diagnostic archives uploaded to console.redhat.com. The redaction layer uses a naive string-match on the literal key name 'password', leaving non-standard credential field names - such as those used by SSSD and Pacemaker - completely unprotected before archive upload. With CVSS PR:L, a threat actor with authenticated access to an organization's Red Hat Insights console can retrieve these cleartext credentials from stored archives. No public exploit identified at time of analysis and not confirmed in CISA KEV.
Unrestricted archive upload in WildFly Core enables authenticated 'deployer' role users to deploy malicious Java archives via HTTP POST requests, potentially achieving arbitrary file reads and further system compromise. Affected products span multiple Red Hat enterprise offerings including JBoss EAP 7 and 8, Red Hat Fuse 7, Process Automation 7, and Single Sign-On 7, all of which embed wildfly-core as a foundational dependency. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Denial of service in WildFly Core (and downstream Red Hat middleware products) allows a remote administrative user to render a server permanently unrecoverable by injecting a malformed payload into the Inet Address field of the Management Model. The injected payload is persisted to standalone.xml, corrupting the configuration file and preventing normal server restart without manual intervention. No public exploit code has been identified at time of analysis, and the vulnerability is limited to users with administrative credentials, reducing its real-world blast radius despite the high availability impact.
NULL pointer dereference in the shim application's dp.c library exposes Red Hat Enterprise Linux 7, 8, and 9 systems using UEFI Secure Boot to a local denial-of-service condition. An attacker with high local privileges and the ability to interact with the shim boot path can trigger the missing NULL pointer check, potentially disrupting the boot process. No public exploit code has been identified at time of analysis, and the low CVSS score of 3.9 reflects the constrained attack prerequisites, though the changed scope (S:C) signals that the impact crosses from the shim component into the broader boot environment.
Code injection in the Feast operator within Red Hat OpenShift AI (RHOAI) allows an authenticated, high-privileged tenant to embed malicious code into their feature repository, which an automated operator process then executes under elevated Kubernetes RBAC permissions. Successful exploitation yields credential theft and full cluster administrative control, representing a critical privilege escalation pathway despite the moderate vendor CVSS score of 5.5. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Sensitive credential disclosure in Red Hat OpenShift AI's odh-model-controller component exposes Kubernetes Secrets - including cloud provider credentials and API keys - across namespace boundaries to any authenticated user holding custom resource creation permissions. The root cause is a confused deputy flaw (CWE-441) in the loadSecret function, which accepts user-controlled namespace input without validation, allowing the controller's elevated cluster-wide RBAC permissions to be turned against secrets in namespaces the attacker could not directly access. No public exploit code or CISA KEV listing is identified at time of analysis.
Red Hat multicluster-global-hub misconfigures topic-level access controls during ManagedClusterMigration, exposing bootstrap kubeconfigs - containing API server tokens - to any managed hub that reads the shared communication topic. A compromised managed hub can silently harvest these credentials, which carry an approximately 9.86-year validity window, enabling long-lived unauthorized access to other managed clusters well beyond the migration event itself. No public exploit has been identified at time of analysis, but the extended token lifetime dramatically amplifies post-compromise dwell risk.
Sensitive guest disk contents are exposed to any local user on Red Hat Enterprise Linux KVM hosts due to `qemu-img` creating new volume image files with world-readable permissions during libvirt storage clone or convert operations. Affected platforms span RHEL 6 through 10 and RHEL for Nvidia 26. No public exploit code has been identified and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog at time of analysis, but the CVSS C:H rating reflects full guest disk exposure to a low-privileged local attacker.
Privilege escalation in Red Hat Advanced Cluster Security 4 (StackRox Central) allows authenticated OIDC token holders to gain unauthorized role assignments through unanchored regular expression matching in the Machine-to-Machine token exchange subsystem. When administrators configure M2M role mappings, RHACS matches incoming OIDC claim values against configured patterns without regex anchors, meaning an attacker whose claim value is a superstring of a mapped pattern - for example, 'superadmin' matching a pattern intended only for 'admin' - receives elevated roles unintentionally. No public exploit code or active exploitation has been identified at this time; the CVSS AC:H rating reflects a genuine complexity barrier requiring attacker knowledge of the target's role mapping configuration.
Signed integer overflow in GIMP's file-fli plugin causes application crashes when processing maliciously crafted FLI animation files, resulting in denial of service. The flaw affects GIMP as packaged on Red Hat Enterprise Linux 6 through 9, where incorrect multiplication of image width and height during buffer size calculation can overflow a signed integer, producing an invalid allocation. No public exploit code or active exploitation has been identified; impact is strictly limited to availability, with no confidentiality or integrity consequences.
Missing authorization on CleanAllRUV and Abort CleanAllRUV LDAP extended operations in 389 Directory Server (Red Hat Directory Server 11-13) allows unauthenticated remote attackers - when the default anonymous access setting is active - to manipulate replication metadata, purge changelog records, and abort administrator-initiated cleanup tasks. The affected operations are replication-maintenance primitives that bypass the authorization layer entirely (CWE-862), meaning no account or session is required under default configuration. No public exploit code or active exploitation in CISA KEV has been identified at time of analysis, but the network-accessible, zero-authentication attack surface in a widely deployed enterprise directory server makes this a notable availability and integrity risk.
Integer overflow in p11-kit's RPC message parser on 32-bit systems allows a local attacker, or any principal with access to a reachable RPC channel, to crash the p11-kit process via a heap out-of-bounds write, resulting in Denial of Service. Affected deployments span Red Hat Enterprise Linux 6 through 10, Red Hat Hardened Images, and OpenShift Container Platform 4. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
SELinux label manipulation via TOCTOU race condition in the policycoreutils fixfiles script allows a local low-privileged attacker to corrupt SELinux mandatory access control labels on arbitrary system files, including security-critical targets such as /etc/shadow. The flaw affects fixfiles when run in relabel or restore mode across all supported Red Hat Enterprise Linux releases (6 through 10), Red Hat Hardened Images, and OpenShift Container Platform 4. No public exploit code or active exploitation has been identified at time of analysis, and exploitation is constrained by both a required race condition win and the need for an administrator to actively invoke fixfiles.
Header injection in openshift/oauth-proxy allows unauthenticated network attackers to impersonate arbitrary users on upstream applications by exploiting authentication-bypass paths. When skip-auth-regex rules are configured, the proxy forwards client-controlled identity headers (X-Forwarded-User, X-Forwarded-Email, X-Forwarded-Access-Token) to upstream services without stripping them, enabling forged identity claims. Affecting Red Hat OpenShift Container Platform 4, this vulnerability is classified under CWE-345 (Insufficient Verification of Data Authenticity) with a CVSS 6.5 base score; no public exploit code or CISA KEV listing has been identified at time of analysis.
Prometheus metric label cardinality exhaustion in Red Hat Build of Keycloak allows any authenticated user to crash the service by flooding its metric store with unique entries. When the Keycloak metrics subsystem is active, failed account operations (such as login attempts referencing nonexistent client IDs) cause raw, unsanitized error strings to be registered as Prometheus label values; because Prometheus stores each unique label combination as a distinct time series, a low-privileged attacker can generate an unbounded number of distinct metric entries, consuming JVM heap until the process crashes or becomes unresponsive. No public exploit code and no CISA KEV listing exist at time of analysis, but the low attack complexity and broad authenticated-user surface make this a realistic denial-of-service risk in any deployment where metrics are enabled.
Keycloak's LDAP storage provider allows delegated administrators to bypass configured search boundaries by supplying a crafted Distinguished Name (DN), exposing account information from unauthorized directory subtrees and triggering unintended user imports into Keycloak local storage. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, Red Hat Data Grid 8, and the JBoss EAP Expansion Pack. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; exploitation is constrained to authenticated delegated administrators with access to the LDAP federation interface.
Persistent denial of service in libkcapi's AIO interface allows a local attacker to permanently hang an affected application thread by exploiting improper error-state handling in _kcapi_aio_read_all(). Affected deployments span Red Hat Enterprise Linux 8, 9, and 10, Red Hat Hardened Images, and Red Hat OpenShift Container Platform 4 - all environments where applications leverage libkcapi's asynchronous cryptographic operations. No public exploit code or active exploitation has been identified at time of analysis; the high attack complexity (AC:H) and local-only attack vector substantially limit real-world risk beyond targeted or insider-threat scenarios.
IV reuse in libkcapi's one-shot symmetric cipher operations allows a remote attacker to weaken data confidentiality for applications processing inputs larger than 64 KiB under stateful modes (CTR or CBC). Affected deployments include Red Hat Enterprise Linux 8, 9, and 10, Red Hat Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation has been identified; the AV:N vector reflects an indirect attack path where an adversary induces a vulnerable application to process specially crafted oversized inputs, enabling ciphertext analysis to expose plaintext relationships or recover data.
Persistent denial of service in dhcp-server (dhcpd) on Red Hat Enterprise Linux 6 through 9 is triggered via a crafted OMAPI lease creation request containing an overly long InfiniBand MAC address, overflowing a buffer in `print_hw_addr()` and crashing the dhcpd daemon in a way that prevents automatic recovery. The official CVSS score of 4.9 with PR:H reflects the assumption that TSIG authentication guards the OMAPI port; however, the description explicitly highlights that TSIG is optional and often absent, reducing the realistic exploitation barrier to unauthenticated network access. No confirmed active exploitation (KEV) or public proof-of-concept exists at time of analysis.
Stack-based out-of-bounds read in stunnel's s_vlog logging function allows remote unauthenticated attackers to crash the service by sending protocol inputs that generate log messages exceeding 1024 bytes via vsnprintf. The primary impact is service disruption (availability), with a limited integrity impact in corner cases where trailing newline characters in the stack buffer can be overwritten with null bytes. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
SSRF bypass in stunnel 5.79 and earlier allows authenticated SOCKS proxy clients to circumvent intended localhost access restrictions by supplying IPv4-mapped IPv6 addresses (e.g., ::ffff:127.0.0.1) or unspecified addresses (0.0.0.0, ::) in proxy requests. Exploitation reaches loopback-bound services on the stunnel host - services deliberately isolated from external network access - potentially exposing internal APIs, administrative interfaces, or other localhost-only endpoints. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog at time of analysis.
Off-by-one memory corruption in popt's poptStuffArgs function allows a local low-privileged attacker to overwrite adjacent memory and potentially execute arbitrary code within any host application that unsafely processes the corrupted argument data. All supported Red Hat Enterprise Linux releases (6 through 10), Red Hat Hardened Images, and OpenShift Container Platform 4 ship the affected library. No public exploit code has been identified and no CISA KEV listing exists; exploitation requires high-complexity triggering conditions, making this a routine patch priority rather than an emergency response item.
Uninitialized heap memory disclosure in SSSD's NSS responder exposes cached directory data and heap layout to local authenticated users on RHEL 6 through 10 and OpenShift Container Platform 4. The sss_nss_protocol_fill_initgr() function pre-allocates a reply buffer sized for all group entries but fails to shrink it when groups are skipped, causing uninitialized heap bytes to be included in the response transmitted back to the requesting client. No public exploit code has been identified at time of analysis, and this is not listed in CISA KEV; however, leaked heap addresses may assist in chained attacks targeting ASLR bypass in sssd_nss.
Forced logout via unsigned backchannel requests affects Red Hat Build of Keycloak when an OIDC identity provider is configured to skip signature validation. Under this non-default configuration, the backchannel logout endpoint in keycloak-services improperly accepts logout requests lacking any cryptographic signature (CWE-347), violating the OIDC backchannel logout specification. An unauthenticated network attacker who possesses knowledge of a target user's session identifiers can submit a forged unsigned logout request, terminating that session without the user's consent. No public exploit or active exploitation (CISA KEV) has been identified; with CVSS 3.7 and EPSS data absent from the input, this is a low-priority availability-only issue gated by a specific non-default configuration.
Path traversal in WildFly's domain mode LocalFileRepository exposes arbitrary files readable by the Domain Controller process to attackers who have already obtained or compromised a slave host controller. The flaw resides in the wildfly-core/deployment-repository component, where getFile() and getConfigurationFile() fail to canonicalize or bound-check caller-supplied paths before resolving them on disk, enabling directory traversal sequences to escape the configured repository root. No active exploitation is confirmed (not listed in CISA KEV) and no public exploit code has been identified, but successful exploitation yields high-confidence access to sensitive artifacts including keystores, credentials, and configuration files.
GNU tar's incremental restore path contains a TOCTOU race condition in dumpdir 'X' rename handling, allowing a local attacker with write access to a backed-up directory to redirect file operations outside the intended extraction root during a privileged restore. Successful exploitation can result in arbitrary file creation, rename, or overwrite - enabling privilege escalation on systems running Red Hat Enterprise Linux 6 through 10 and Red Hat Hardened Images. No public exploit is identified at time of analysis, and no CISA KEV listing exists; the CVSS score of 4.4 reflects the constrained attack prerequisites including a required race window and administrator-initiated restore.
Authentication bypass in 389 Directory Server (Red Hat Directory Server 11-13) allows a network-connected user holding valid credentials for an administratively locked account to retain an authenticated LDAP session, defeating account-lock as an access-revocation control. The SASL PLAIN bind handler installs connection-level authenticated state before executing the account-lock check; when the lock check fails, only the error is returned to the client while the internal authenticated state on that connection persists unrevertd. No public exploit has been identified at time of analysis and no CISA KEV listing exists, but the real-world impact is highest in incident-response and employee-offboarding scenarios that rely on directory lock as the primary revocation mechanism.
GNU tar's --one-top-level extraction mode fails to confine hardlink targets to the designated top-level directory, allowing a crafted archive to plant hardlinks that escape the intended extraction boundary. When combined with a preexisting symbolic link already present under the working directory, an attacker who can induce a victim to extract a malicious archive may read or write files outside the intended extraction scope on systems running affected RHEL versions (6 through 10) and Red Hat Hardened Images. No public exploit has been identified at time of analysis, and exploitation requires both user interaction and a specific environmental pre-condition, keeping real-world risk moderate despite GNU tar's ubiquitous deployment.
Out-of-bounds read in SSSD's NSS responder allows a local user with standard privileges to crash the SSSD process by sending a crafted GETHOSTBYADDR request, causing system-wide denial of authentication and name resolution services. The vulnerable function `sss_nss_protocol_parse_addr()` fails to validate the `addrlen` field against the actual remaining packet body size, enabling heap over-read and process termination. No public exploit code or active exploitation has been identified at time of analysis, and this vulnerability is not listed in CISA KEV.
Heap-based out-of-bounds write in GIMP's PAA (Paint Shop Pro Array) file format plugin allows a remote attacker to potentially execute arbitrary code on a victim's system by tricking the user into opening a specially crafted PAA image. The flaw resides in the decode_lzss() decompression function, which writes data beyond the bounds of the allocated heap buffer, enabling heap metadata corruption. No public exploit or CISA KEV listing exists at time of analysis, but the RCE-tagged impact and buffer-write primitive make this a higher-severity risk than the CVSS 5.5 score suggests; the CVSS impact metrics reflect only availability (A:H) while the description and tags indicate arbitrary code execution potential - a notable discrepancy to investigate.
Stack-based buffer overflow in GIMP's file-png plugin on Red Hat Enterprise Linux 6 through 9 causes the application to crash when a user opens a crafted Animated PNG (APNG) image containing an oversized tRNS chunk, resulting in a Denial of Service limited to the affected user session. Exploitation requires local file access and active user interaction - a remote attacker would rely on social engineering (phishing, malicious download) to deliver the file. No active exploitation has been confirmed by CISA KEV, no public exploit code is identified at time of analysis, and EPSS data is unavailable in source intelligence.
Client policy enforcement in Red Hat Build of Keycloak can be bypassed by an authenticated user holding client management permissions, allowing non-compliant OAuth clients to persist in a realm despite administrator-configured security hardening. The bypass exploits improper client state evaluation during update operations: an attacker creates a public client - which passes policy validation - and then updates it to a confidential client type, skipping the re-evaluation that would normally reject a non-compliant confidential client. No public exploit code has been identified and this CVE is not listed in CISA KEV; however, the low attack complexity and broad deployment of Keycloak in enterprise IAM infrastructure elevate its practical significance.
Time-based authorization policy bypass in Red Hat Build of Keycloak permits any low-privileged authenticated user to inject a fabricated timestamp into their authorization request, causing Keycloak's Authorization Services engine to evaluate the forged value instead of the actual server clock. This fully defeats time-based access controls - such as business-hours restrictions - across affected Red Hat products including Keycloak, Single Sign-On 7, Data Grid 8, and JBoss EAP Expansion Pack. No public exploit code has been identified and this CVE is not listed in CISA KEV, but the CVSS High integrity impact accurately reflects that time-gated authorization controls are rendered entirely ineffective against any valid account holder.
The full-scope-disabled client-policy executor in Red Hat Build of Keycloak silently skips enforcement when the fullScopeAllowed attribute is absent from a client registration or update request, allowing a delegated user to create OAuth/OIDC clients with unrestricted scope access. Affected platforms span Red Hat Build of Keycloak, Red Hat Single Sign-On 7, Red Hat Data Grid 8, and JBoss EAP Expansion Pack. An attacker holding delegated registration privileges (CVSS PR:L) can exploit this to issue tokens containing unauthorized role mappings, effectively escalating their effective permissions within any application trusting those tokens. No public exploit code or CISA KEV entry has been identified at time of analysis.
Incomplete HTTP parameter pollution validation in Keycloak's keycloak-services component exposes OIDC authentication flows to session fixation and account confusion attacks. The security check inspects only the query string of redirect URLs while ignoring the URL fragment, enabling an attacker to inject duplicate security parameters when a client is configured with a wildcard redirect URI. No public exploit has been identified at time of analysis; the CVSS score of 3.4 (AC:H, UI:R) correctly reflects that exploitation requires both a permissive wildcard redirect URI configuration and a non-spec-compliant client application that trusts attacker-injected parameters over Keycloak-issued values.
Wildcard domain validation in Keycloak's keycloak-services component can be bypassed by an attacker who controls their connection's reverse DNS, enabling unauthorized client registration or modification against a Keycloak realm. The flaw stems from the system accepting any hostname that merely ends with the configured domain suffix (e.g., 'attackerexample.com' satisfying a '*.example.com' restriction) rather than enforcing true subdomain membership. Exploitation requires high attack complexity due to the reverse DNS control prerequisite, and no public exploit or CISA KEV listing has been identified at the time of analysis.
Incorrect authorization in Keycloak's group policy evaluation allows a low-privileged authenticated user to bypass group membership checks and gain unauthorized access to administrative functions or protected resources. The root cause is a string prefix comparison used to verify child-group membership under an 'extend to child groups' policy: a user in a group whose name shares a leading prefix with a privileged group (e.g., '/admins-external' matching a policy scoped to '/admins') is incorrectly treated as a legitimate child-group member. The CVSS vector (PR:L, I:H) confirms this is an authenticated integrity-bypass with high impact. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Redirect URI policy bypass in Keycloak's secure-client-uris executor enables interception of OAuth authorization codes over unencrypted HTTP connections. The flaw exists because the executor performs only a prefix-string comparison on the redirect URI rather than properly parsing and validating the host component, allowing a specially crafted domain name to satisfy the HTTPS enforcement check while pointing to an attacker-controlled HTTP endpoint. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, and related Red Hat middleware products. No public exploit code or CISA KEV listing has been identified at time of analysis.
Keycloak's OIDC token introspection endpoint incorrectly discloses the full set of JWT claims to confidential clients inspecting tokens that were not issued for them. Any confidential client configured to receive signed JWT introspection responses can submit a foreign token, receive an 'inactive' status confirmation, and simultaneously receive the complete signed JWT payload containing sensitive user attributes and claims - effectively bypassing the audience isolation that OIDC introspection is designed to enforce. No active exploitation has been confirmed (not listed in CISA KEV), and no public proof-of-concept code has been identified at time of analysis, but the low attack complexity and network accessibility via a standard API endpoint make this a meaningful confidentiality risk in multi-tenant or multi-client Keycloak deployments.
Broken access control in Keycloak's RoleContainerResource component allows delegated administrators with manage-realm permissions to remove child roles from built-in admin roles via name-based endpoints in the admin REST API that skip proper authorization checks. Affected distributions include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, Red Hat JBoss EAP Expansion Pack, and Red Hat Data Grid 8. An attacker exploiting this flaw can degrade or disrupt administrative functions within a realm by stripping essential role assignments from built-in admin roles, effectively undermining the role-based access control structure of the affected deployment. No public exploit code and no CISA KEV listing are associated with this CVE at time of analysis.
SAML HTTP-Redirect binding in Keycloak allows network-based attackers to inject malicious parameters into authentication requests targeting clients configured with wildcard redirect URLs. When a victim user completes authentication, Keycloak appends its legitimate SAML response to the attacker-controlled URL parameters, which can cause susceptible service providers to process the attacker's data instead of the real login assertion - potentially resulting in the victim being logged into the wrong account. No public exploit is identified at time of analysis, and the CVSS score of 3.4 (Low) reflects the high attack complexity and limited integrity-only impact.
Token revocation bypass in Keycloak's TokenManager component allows sessions and user data access to persist after administrative invalidation. The flaw (CWE-862: Missing Authorization) causes client-level 'not-before' revocation policies to be silently skipped when a realm-level revocation policy with an older, non-zero timestamp is already in place - causing the revocation to produce no effect. Authenticated token holders (PR:L) can continue refreshing sessions and querying user information APIs despite explicit administrative revocation. No public exploit identified at time of analysis; KEV status is not confirmed.
Insecure file permissions in ansible-collection-redhat-leapp expose PostgreSQL backup archives to local non-root users on managed RHEL 9 and RHEL 10 nodes. When the `leapp_old_postgresql_data` remediation option is invoked with elevated privileges, the resulting backup archive is written with world-readable or group-readable permissions (CWE-732), allowing any local non-root user on that managed node to extract the full contents of the archived PostgreSQL data. No public exploit has been identified at time of analysis, and exploitation requires local authenticated access to the managed node.
The ansible-collection-redhat-leapp package exposes Ansible controller-side sensitive files to attacker-controlled managed nodes through a manipulated Leapp upgrade report. An attacker who has already obtained privileged write access to a managed node's Leapp report can craft malicious report content that, when an operator executes a specific remediation task, causes the Ansible controller to read and copy its own local files - including private keys and credentials - to the attacker-controlled managed node. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the CVSS 3.1 score of 6.2 reflects real-world risk limited by the high privilege prerequisite and required operator interaction.
Denial of service in Samba's Kerberos KDC password change (kpasswd) service allows authenticated remote attackers to crash the KDC process by submitting specially crafted, malformed ASN.1-encoded password change requests. The server miscalculates the structure size of the incoming request and reads up to six bytes beyond the end of the allocated buffer; when this read strikes unmapped memory, the KDC process terminates rather than simply failing gracefully. No public exploit has been identified and no CISA KEV listing exists, but the disruption of a KDC in an Active Directory or Samba domain environment carries significant operational impact since authentication for the entire domain depends on KDC availability.
Samba's internal DNS server inserts unauthenticated TKEY registration requests into the TKEY name cache before rejecting them, allowing a remote unauthenticated attacker to exhaust the cache by flooding it with arbitrary TKEY names. Eviction of legitimate cache entries blocks TSIG-authenticated DNS query processing, producing a targeted denial of service against Active Directory environments relying on Samba's built-in DNS backend. No public exploit code or CISA KEV listing has been identified at time of analysis; a vendor patch is available from both Samba upstream and Red Hat.
Server-side request forgery in Dogtag PKI's ACME responder enables unauthenticated ACME account holders to direct the certificate server to make arbitrary HTTP GET requests to internal network addresses. The validator incorrectly accepts IP address literals as valid DNS identifiers and follows HTTP redirects without enforcing RFC-compliant public-address filtering, allowing internal network reconnaissance. When the InMemory database backend is in use, the response body returned by internal services is exposed to the attacker through ACME challenge error messages, compounding the confidentiality impact. No public exploit code or active exploitation has been identified at time of analysis.
Path traversal in the Performance Co-Pilot (PCP) pmproxy logger servlet on Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4 permits unauthenticated remote attackers to create arbitrary files and directories on the host filesystem by supplying a crafted hostname value in requests to the service. The primitive is write-only - no file contents can be read - but an attacker can abuse it to corrupt directory structures or exhaust disk space, leading to denial of service. No public exploit code has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog.
Remote unauthenticated denial of service and memory disclosure in the Performance Co-Pilot (PCP) pmproxy service affects Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. An out-of-bounds read (CWE-125) in the pmLogLoadInDom() function can be triggered by a specially crafted network request, causing the pmproxy process to crash and potentially leaking sensitive data from process memory. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Missing authorization in Keycloak's administrative API allows a scoped administrator to exceed their privilege boundary by linking identity providers to organizations they are not authorized to manage. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, and related Red Hat products. An administrator who holds identity provider management permissions but lacks organization management rights can silently reconfigure authentication flows for organizations outside their administrative scope, potentially redirecting user logins through attacker-controlled providers. No public exploit code exists and this vulnerability is not listed in CISA KEV at time of analysis.
Client policy enforcement in Keycloak is bypassable by any user holding client management privileges who exploits a group-name collision across the group hierarchy. Because the policy engine resolves group membership by display name rather than unique identifier, an attacker can create or join a group in a different part of the hierarchy that shares a name with a privileged policy group, then register or update OAuth/OIDC clients without satisfying the required security hardening profiles. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV.
Out-of-bounds heap read in GNU Binutils linker when processing 32-bit XCOFF files allows local attackers to disclose heap memory and cause denial of service. Affects Red Hat Enterprise Linux 6 through 10, Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation identified at time of analysis; EPSS data unavailable.
Authorization bypass in Red Hat Certificate System's CA renewal path allows an authenticated user to renew a certificate belonging to a different realm without the required realm-based authorization check. Affects versions 9, 10, and 11 of the Certificate System on Red Hat Enterprise Linux 6 through 10. No evidence of active exploitation or public exploit code exists at the time of analysis, and EPSS probability is low (0.21%).
Information disclosure in Red Hat Build of Keycloak allows restricted administrators to view private user details (names, email addresses) via the role-users endpoint, due to a missing permission check. The flaw affects the keycloak-services library, exposing sensitive data to low-privilege users. No active exploitation or public exploit is known, and EPSS indicates low exploitation probability.
Information disclosure in the Keycloak Admin REST API allows a delegated administrator with view-only permissions to retrieve the resolved client secret from a secure vault instead of the vault placeholder, exposing sensitive credentials. Affected Red Hat builds include Keycloak, Single Sign-On 7, Data Grid 8, and JBoss EAP expansion pack. No active exploitation or public exploit is known; EPSS probability is low (0.21%).
Local information disclosure in accountsservice on Red Hat Enterprise Linux allows systemd-homed users to read arbitrary files via the SetIconFile handler. A proof-of-concept exists, but exploitation requires a local account managed by systemd-homed, limiting impact
Denial of service in dbus-broker allows a local attacker to crash the user session bus broker when file descriptor limits are exhausted. Affected products include Red Hat Enterprise Linux 9/10, Red Hat OpenShift Container Platform 4, and Red Hat Hardened Images where dbus-broker is deployed. No active exploitation or public exploit code is known, and EPSS indicates low exploitation probability (0.11%).
Server-Side Request Forgery (SSRF) in Red Hat Quay 3's notification webhook feature allows repository administrators to weaponize the Quay worker process as an internal network proxy. By supplying attacker-controlled URLs to the Slack or generic webhook notification handlers, a repository admin can cause the Quay backend to issue POST requests to RFC-1918 addresses, cloud metadata endpoints (e.g., AWS IMDSv1 at 169.254.169.254), or other infrastructure that should be network-isolated from the application. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
Red Hat Certificate System (RHCS) 9 is susceptible to a resource exhaustion denial-of-service condition triggered by unauthenticated remote attackers flooding its TLS-exposed HTTP endpoint. Repeated requests cause the underlying Java process to exhaust available heap memory, resulting in an Out of Memory crash that takes the certificate authority service offline. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity and absence of authentication requirements make this a realistic threat to any internet- or intranet-exposed RHCS deployment.
Out-of-bounds heap read in gdk-pixbuf's ICO parser exposes heap memory content through rendered image output, affecting Red Hat Enterprise Linux 6 through 10. When processing a crafted ICO file whose pixel indices exceed the defined palette size, the library reads beyond the palette array boundary - heap bytes are treated as palette entries and rendered as RGB pixel values in the output image, enabling an attacker to extract heap content by analyzing the rendered result. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but server-side image processing pipelines that return rendered output to untrusted callers represent a realistic exposure path.
Format string vulnerability in GNU nano's multi-buffer error message handling allows a local low-privileged attacker to cause stack information disclosure, denial of service via crash, or potentially achieve arbitrary memory writes. The flaw (CWE-134) is triggered when a user opens multiple files at startup, one of which carries a specially crafted name containing printf format specifiers and another triggers an ALERT-level error - causing nano to misinterpret the filename as a format string. Reported by Red Hat and scoped to RHEL 6 through 10 and OpenShift Container Platform 4, no public exploit or CISA KEV listing exists at time of analysis.
PKCE bypass in librest allows OAuth 2.0 client impersonation by exploiting a cryptographically weak pseudo-random number generator. The library's code verifier generation for PKCE (RFC 7636) uses GLib's GRand function - a non-cryptographic PRNG with a 32-bit seed space - rather than a CSPRNG, enabling a positioned attacker to recover the PRNG seed and reconstruct the code verifier to hijack the token exchange. Rated CVSS 6.8 with high confidentiality and integrity impact; no public exploit or CISA KEV listing identified at time of analysis.
Symlink-following vulnerability (CWE-59) in systemd-tmpfiles allows a local, low-privileged user to redirect privileged file write operations to an attacker-controlled path on affected Red Hat Enterprise Linux systems. The flaw resides in the path resolution logic within chase.c, where a safety check incorrectly treats all transitions away from the root user as inherently safe - failing to detect attacker-placed symlinks at tmpfiles.d target path components. Exploitation is constrained by high attack complexity requiring a specific non-default tmpfiles.d configuration, and no public exploit code or CISA KEV listing has been identified at time of analysis.
Heap buffer overflow in Red Hat Directory Server (389-ds-base) exposes LDAP services to remote unauthenticated denial of service or potential arbitrary memory write via malformed DN input. When a Distinguished Name containing a legacy-quoted value is processed, the server fails to close the associated heap allocation, permitting a subsequent operation to reference the same memory pointer - a classic heap confusion primitive. No public exploit has been identified at time of analysis, and this vulnerability is not listed in CISA KEV, though the network-accessible unauthenticated attack surface warrants prompt patching for any externally reachable Directory Server deployment.
Remote code execution in the submariner-operator component of Red Hat Advanced Cluster Management for Kubernetes 2.x allows a cluster administrator-or any user holding RBAC permissions to modify the Submariner Custom Resource-to reference an unvalidated, attacker-controlled container image path, causing the operator to deploy and execute arbitrary code with elevated privileges across the entire cluster, including control-plane nodes. The root cause (CWE-20: Improper Input Validation) is the absence of image path sanitization or verification before the operator acts on the Submariner CR field, enabling privilege escalation beyond the user's intended cluster boundary. No public exploit code and no CISA KEV listing have been identified at time of analysis, but the Changed Scope with full C:H/I:H/A:H impact ratings signal potential for complete cluster compromise once the high-privilege prerequisite is met.
Cleartext storage of a long-lived broker service account bearer token in the Submariner Custom Resource specification exposes full mesh network control to any Kubernetes principal with CR read access. Red Hat Advanced Cluster Management for Kubernetes 2 (RHACM 2) is confirmed affected via CPE. An attacker who retrieves the token - through a routine `kubectl get` invocation or direct etcd access - gains unrestricted authority to manage Submariner endpoints, secrets, and cross-cluster network resources, constituting a complete compromise of the multi-cluster network plane. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Cleartext storage of the IPsec pre-shared key (PSK) in the Submariner Custom Resource exposes the cryptographic secret used to secure all inter-cluster communication in Red Hat Advanced Cluster Management for Kubernetes 2 deployments. Any principal with low-privilege read access to the Submariner CR object within the Kubernetes cluster can retrieve the PSK and use it to passively decrypt IPsec-encrypted traffic flowing between every cluster in the connected mesh - not just the cluster where access was obtained (CVSS scope change S:C). No public exploit code exists and the vulnerability is not listed in CISA KEV, but the architectural impact is severe: a single stolen key compromises the confidentiality of all inter-cluster traffic simultaneously.
Credential exposure in Red Hat Advanced Cluster Management for Kubernetes 2.x allows any local user with access to a must-gather diagnostic archive to read proxy basic-auth credentials in plaintext. The must-gather component dumps the cluster Proxy object in raw form, bypassing the redaction logic that oc inspect would normally apply to sanitize sensitive fields before archiving. No public exploit code exists and this is not listed in CISA KEV, but the CVSS AV:L/PR:L vector confirms real-world exposure is bounded to archive access rather than remote exploitation.
Cleartext credential exposure in Red Hat Advanced Cluster Management for Kubernetes affects the must-gather diagnostic tool, which collects ACM wrapper Custom Resources containing embedded Secret data without scrubbing sensitive fields. Any administrator who runs must-gather to diagnose cluster issues inadvertently captures credentials and tokens in the resulting archive, which may then be stored, shared, or transmitted without awareness of the embedded secrets. No public exploit identified at time of analysis, but the information disclosure risk is compounded by the routine, trust-assumed nature of diagnostic archive handling.
Out-of-bounds memory read in BlueZ's AVRCP implementation allows a physically proximate attacker - within Bluetooth radio range - to crash the bluetoothd daemon and potentially leak heap memory contents by sending a malformed GetFolderItems response. The flaw resides in parse_media_element() and parse_media_folder(), which fail to validate packet length fields before reading. Exploitation requires the victim to interactively pair with the attacker-controlled malicious Bluetooth device. No public exploit code or CISA KEV listing has been identified at time of analysis.
Red Hat Quay's notification API exposes sensitive integration secrets - including webhook URLs, Slack tokens, and email addresses - to any authenticated repository administrator who can enumerate or guess a target notification's UUID. The flaw is an Insecure Direct Object Reference (CWE-639): the notification UUID acts as the sole access control key, with no ownership check verifying that the requesting admin belongs to the repository whose notification is being accessed. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, but the confidentiality impact is High per CVSS due to the sensitivity of the exposed secrets.
LDAP injection in Red Hat Quay 3's external LDAP authentication handler allows unauthenticated network attackers to inject filter metacharacters into LDAP queries when the directory server returns a referral response. Exploitation enables user-existence oracle attacks against the referral Directory Name and can potentially influence which Distinguished Name is used during password binding in multi-domain Active Directory environments. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog; however, the network-accessible attack vector and lack of authentication requirement elevate practical concern for organizations using LDAP-integrated Quay deployments.
JWT claim validation failures in Red Hat Quay's federated robot account and SSO authentication pathways allow an attacker who already holds a legitimately-issued token from the same configured identity provider to bypass audience (`aud`), authorized party (`azp`), and subject (`sub`) restrictions. Affected deployments include Red Hat Quay 3 and Red Hat OpenShift Update Service across all currently tracked versions. Successful exploitation yields unauthorized access to registry resources beyond the attacker's intended scope, including potential cross-account or cross-namespace read and write access within the Quay instance. No public exploit code has been identified and this CVE is not currently listed in the CISA KEV catalog.
Denial of service in dnsmasq's DNSSEC validation code allows an attacker who operates any DNSSEC-signed authoritative zone to permanently hang the dnsmasq process with a single crafted DNS response, killing all DNS resolution for every client served by that instance. Affected deployments include dnsmasq as packaged in Red Hat Enterprise Linux 6 through 10 and Red Hat OpenShift Container Platform 4. No public exploit code or active exploitation has been identified at time of analysis; the assigned CVSS score of 4.4 (Medium) carries a notable inconsistency between the stated local attack vector and the network-delivered attack mechanism described.
Undertow's HTTP response header writing path silently truncates 16-bit Unicode characters to 8-bit bytes via a narrowing cast in the `writeString()` method, enabling remote unauthenticated attackers to inject ASCII control characters or special symbols into response headers when an application passes unsanitized user-controlled input into those headers. Affected Red Hat distributions include RHEL 8/9/10, JBoss EAP 7, Red Hat Build of Apache Camel for Spring Boot 4, and Red Hat Single Sign-On 7, as reported by Red Hat via Bugzilla #2516038. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Privileged file corruption and denial of service in sblim-sfcb (Small Footprint CIM Broker) on Red Hat Enterprise Linux 6 through 10 is achievable by a local low-privileged attacker exploiting a symlink-based race condition during privileged instance migration. The SFCB daemon writes to a temporary file in /tmp without atomic safety guarantees, allowing an attacker who repeatedly races a symbolic link into place to redirect that privileged write to an arbitrary file path. No public exploit has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
Out-of-bounds memory read in sblim-sfcb's provider-manager IPC message parser allows a local low-privileged attacker to crash the provider-manager process, causing denial of service and potentially leaking limited adjacent memory contents. The vulnerability stems from unsafe deserialization of attacker-controlled IPC messages without adequate boundary validation, affecting sblim-sfcb as shipped across Red Hat Enterprise Linux versions 6 through 10. No public exploit code or active exploitation has been identified at time of analysis, and exploitation is constrained to local system access.
Insecure temporary file creation in sblim-cmpi-base provider registration scripts exposes Red Hat Enterprise Linux 6 through 10 to a local symlink attack, enabling a low-privileged user to redirect privileged file writes to arbitrary paths. When registration scripts execute under elevated (root) privileges, an attacker who pre-positions a symlink in a world-writable directory can cause those scripts to overwrite root-owned files, disrupting system services or integrity. No public exploit code has been identified at time of analysis, and exploitation requires both local access and favorable timing, but the integrity and availability impact on a compromised host are rated high by the vendor.
The iscsiuio DHCP parser in open-iscsi crashes when processing maliciously crafted DHCP reply packets, disrupting iSCSI storage connectivity or network boot on affected hosts. An integer underflow (CWE-191) in the IPv4/UDP DHCP reply parsing path triggers an out-of-bounds read, causing the iscsiuio process to terminate; impact is limited to availability with no confidentiality or integrity exposure. No public exploit code or active exploitation has been identified at time of analysis, and the adjacent-network attack vector constrains the realistic attacker population to the same Layer-2 segment as the target.
Excessive Kubernetes RBAC privileges in the insights-client ServiceAccount within Red Hat Advanced Cluster Management for Kubernetes 2 expose all cluster Secrets to any attacker who compromises the pod or obtains its token. The ServiceAccount is bound to a ClusterRole granting cluster-wide get, list, and watch on all Secrets, far exceeding the single Secret the component actually requires. If the insights-client pod is breached, an attacker can read every Secret across the hub cluster - including managed-cluster kubeconfigs - enabling lateral movement to downstream managed clusters. No public exploit code has been identified at time of analysis, and this CVE is not listed in CISA KEV.
Integer underflow in open-iscsi's iscsiuio daemon crashes the process when parsing malformed DHCPv6 Advertise packets with a truncated UDP length field, disrupting iSCSI storage connectivity. Systems running Red Hat Enterprise Linux 9 and 10 with iscsiuio actively engaged in a DHCPv6 exchange are exploitable by any unauthenticated attacker on the same adjacent network segment. No active exploitation (CISA KEV) or public proof-of-concept has been identified at time of analysis; real-world impact is highest in shared or multi-tenant storage network environments where adjacency cannot be guaranteed.
Denial of service in open-iscsi's iscsiuio daemon allows an unauthenticated attacker on the same local network segment to render the daemon permanently unresponsive by sending a single crafted ICMPv6 Router Advertisement carrying a zero-length option, triggering an infinite loop and sustained CPU exhaustion. Affected deployments include Red Hat Enterprise Linux 9 and 10 systems where iscsiuio is active for iSCSI hardware offload. A secondary out-of-bounds read risk exists when a short IPv6 payload is processed, though no memory corruption or data exposure has been confirmed from available intelligence; no public exploit code or CISA KEV listing has been identified at time of analysis.
Credential interception in Red Hat Multicluster Engine for Kubernetes (MCE) exposes newly rotated provider credentials through an authorization bypass in the provider-credential-controller component. An attacker with specific hub cluster permissions and prior knowledge of a credential value can manipulate `copiedFrom` labels to hijack the credential rotation process, gaining unauthorized read access to sensitive credentials scoped across managed clusters. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but the high confidentiality impact and cross-cluster scope change make this a meaningful risk in mixed-trust MCE deployments.
Integer underflow in GStreamer's avidemux element allows a remote unauthenticated attacker to trigger heap out-of-bounds read and write, heap memory disclosure, and application crash by delivering a crafted AVI file containing a malformed FUJIFILM strd chunk. The gst_avi_demux_parse_strd() function decrements its remaining-length counter by fixed offsets without bounds checking, causing unsigned integer wraparound for payloads of exactly 106 or 107 bytes. Because avidemux is auto-plugged by GStreamer's high-level components (playbin, decodebin, gst-discoverer), any application that opens or previews a media file - including GNOME Files, Nautilus, Totem, and many others - can trigger the vulnerability without user awareness. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis; a vendor-released patch is available in gst-plugins-good 1.28.6.
Out-of-bounds read in GStreamer's avidemux plugin (gst-plugins-good) allows a remote, unauthenticated attacker to crash media-processing applications and potentially leak memory contents by supplying a crafted AVI file. The flaw resides in gst_avi_demux_riff_parse_vprp(), where the count of video field descriptors is derived by dividing remaining buffer size by an attacker-controlled vprp->fields value rather than the struct size, causing the parser to treat more descriptors as valid than the buffer holds. User interaction is required to trigger the bug (the victim must open or stream the malicious AVI via playbin or decodebin), and the primary confirmed impact is denial of service; limited information disclosure is also possible. No public exploit or CISA KEV listing has been identified at time of analysis.
Use-After-Free vulnerabilities in the GNU linker (ld) component of binutils crash the linker process when processing crafted object or archive files during LTO-enabled linking on Red Hat Enterprise Linux systems. The flaws exist at three distinct dereference points in add_archive_element() in ld/ldmain.c, where plugin_maybe_claim() frees the BFD object but the caller retains dangling pointers that are subsequently accessed. The attack surface is confined to build-time environments, with the primary realistic threat being a supply chain attack introducing a malicious object file into CI/CD pipelines or developer build systems; no public exploit code or active exploitation has been confirmed at time of analysis.
Heap corruption via double-free in 389-ds-base's LDAP control parsing allows an unauthenticated remote attacker to crash the directory service with a single crafted BIND request. The flaw resides in `get_ldapmessage_controls_ext()`, which frees a parsed controls array when rejecting an unknown critical Session Tracking control but fails to clear the corresponding SLAPI_REQCONTROLS pblock slot - causing operation teardown to free the same pointer a second time. Affected deployments include Red Hat Directory Server 11 through 13 and the 389-ds-base package across all supported RHEL versions (6-10). No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog; the CVSS AC:H rating reflects that reliable heap exploitation requires specific memory layout conditions rather than a trivially repeatable one-shot crash.
Cross-namespace Secret manipulation in the multicloud-operators-channel component of Red Hat Advanced Cluster Management for Kubernetes 2 (RHACM) enables an authenticated low-privileged user holding specific channel-related permissions to read or modify Kubernetes Secrets outside their authorized namespace scope. The CVSS S:C (Changed Scope) metric confirms the flaw crosses namespace trust boundaries - a critical boundary in multi-tenant Kubernetes environments - potentially exposing credentials, service account tokens, or application secrets belonging to other tenants, and enabling privilege escalation. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Open redirect in the oauth-server component of Red Hat OpenShift Container Platform 4 allows a remote attacker to craft a malicious OAuth grant URL that, upon interaction by an authenticated user, silently redirects that user to an attacker-controlled site. The root cause is the absence of server-side validation on the 'then' parameter in the grant approval handler (CWE-601), making every OpenShift OAuth endpoint a potential phishing launcher. No public exploit code or CISA KEV listing has been identified at time of analysis; the CVSS 4.3 Medium score reflects the required user interaction as the primary limiting factor.
HTTP request smuggling in Undertow's ChunkReader component enables unauthenticated remote attackers to inject out-of-sync requests, bypassing upstream security controls such as authentication layers or reverse-proxy ACLs. Affected deployments include JBoss EAP 7, WildFly, Red Hat Enterprise Linux 8/9/10, Red Hat Data Grid 8, Red Hat Fuse 7, Red Hat Single Sign-On 7, and several Apache Camel-based Red Hat products. No confirmed active exploitation or public proof-of-concept has been identified at time of analysis; the CVSS 5.3 Medium score reflects limited direct impact, though real-world risk in proxy-fronted architectures is meaningfully higher than the score alone suggests.
Cleartext credential exposure in Red Hat insights-core allows SSSD LDAP bind passwords (ldap_default_authtok) and Pacemaker fence device credentials to be included unredacted in diagnostic archives uploaded to console.redhat.com. The redaction layer uses a naive string-match on the literal key name 'password', leaving non-standard credential field names - such as those used by SSSD and Pacemaker - completely unprotected before archive upload. With CVSS PR:L, a threat actor with authenticated access to an organization's Red Hat Insights console can retrieve these cleartext credentials from stored archives. No public exploit identified at time of analysis and not confirmed in CISA KEV.
Unrestricted archive upload in WildFly Core enables authenticated 'deployer' role users to deploy malicious Java archives via HTTP POST requests, potentially achieving arbitrary file reads and further system compromise. Affected products span multiple Red Hat enterprise offerings including JBoss EAP 7 and 8, Red Hat Fuse 7, Process Automation 7, and Single Sign-On 7, all of which embed wildfly-core as a foundational dependency. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Denial of service in WildFly Core (and downstream Red Hat middleware products) allows a remote administrative user to render a server permanently unrecoverable by injecting a malformed payload into the Inet Address field of the Management Model. The injected payload is persisted to standalone.xml, corrupting the configuration file and preventing normal server restart without manual intervention. No public exploit code has been identified at time of analysis, and the vulnerability is limited to users with administrative credentials, reducing its real-world blast radius despite the high availability impact.
NULL pointer dereference in the shim application's dp.c library exposes Red Hat Enterprise Linux 7, 8, and 9 systems using UEFI Secure Boot to a local denial-of-service condition. An attacker with high local privileges and the ability to interact with the shim boot path can trigger the missing NULL pointer check, potentially disrupting the boot process. No public exploit code has been identified at time of analysis, and the low CVSS score of 3.9 reflects the constrained attack prerequisites, though the changed scope (S:C) signals that the impact crosses from the shim component into the broader boot environment.
Code injection in the Feast operator within Red Hat OpenShift AI (RHOAI) allows an authenticated, high-privileged tenant to embed malicious code into their feature repository, which an automated operator process then executes under elevated Kubernetes RBAC permissions. Successful exploitation yields credential theft and full cluster administrative control, representing a critical privilege escalation pathway despite the moderate vendor CVSS score of 5.5. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Sensitive credential disclosure in Red Hat OpenShift AI's odh-model-controller component exposes Kubernetes Secrets - including cloud provider credentials and API keys - across namespace boundaries to any authenticated user holding custom resource creation permissions. The root cause is a confused deputy flaw (CWE-441) in the loadSecret function, which accepts user-controlled namespace input without validation, allowing the controller's elevated cluster-wide RBAC permissions to be turned against secrets in namespaces the attacker could not directly access. No public exploit code or CISA KEV listing is identified at time of analysis.
Red Hat multicluster-global-hub misconfigures topic-level access controls during ManagedClusterMigration, exposing bootstrap kubeconfigs - containing API server tokens - to any managed hub that reads the shared communication topic. A compromised managed hub can silently harvest these credentials, which carry an approximately 9.86-year validity window, enabling long-lived unauthorized access to other managed clusters well beyond the migration event itself. No public exploit has been identified at time of analysis, but the extended token lifetime dramatically amplifies post-compromise dwell risk.
Sensitive guest disk contents are exposed to any local user on Red Hat Enterprise Linux KVM hosts due to `qemu-img` creating new volume image files with world-readable permissions during libvirt storage clone or convert operations. Affected platforms span RHEL 6 through 10 and RHEL for Nvidia 26. No public exploit code has been identified and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog at time of analysis, but the CVSS C:H rating reflects full guest disk exposure to a low-privileged local attacker.
Privilege escalation in Red Hat Advanced Cluster Security 4 (StackRox Central) allows authenticated OIDC token holders to gain unauthorized role assignments through unanchored regular expression matching in the Machine-to-Machine token exchange subsystem. When administrators configure M2M role mappings, RHACS matches incoming OIDC claim values against configured patterns without regex anchors, meaning an attacker whose claim value is a superstring of a mapped pattern - for example, 'superadmin' matching a pattern intended only for 'admin' - receives elevated roles unintentionally. No public exploit code or active exploitation has been identified at this time; the CVSS AC:H rating reflects a genuine complexity barrier requiring attacker knowledge of the target's role mapping configuration.
Signed integer overflow in GIMP's file-fli plugin causes application crashes when processing maliciously crafted FLI animation files, resulting in denial of service. The flaw affects GIMP as packaged on Red Hat Enterprise Linux 6 through 9, where incorrect multiplication of image width and height during buffer size calculation can overflow a signed integer, producing an invalid allocation. No public exploit code or active exploitation has been identified; impact is strictly limited to availability, with no confidentiality or integrity consequences.
Missing authorization on CleanAllRUV and Abort CleanAllRUV LDAP extended operations in 389 Directory Server (Red Hat Directory Server 11-13) allows unauthenticated remote attackers - when the default anonymous access setting is active - to manipulate replication metadata, purge changelog records, and abort administrator-initiated cleanup tasks. The affected operations are replication-maintenance primitives that bypass the authorization layer entirely (CWE-862), meaning no account or session is required under default configuration. No public exploit code or active exploitation in CISA KEV has been identified at time of analysis, but the network-accessible, zero-authentication attack surface in a widely deployed enterprise directory server makes this a notable availability and integrity risk.
Integer overflow in p11-kit's RPC message parser on 32-bit systems allows a local attacker, or any principal with access to a reachable RPC channel, to crash the p11-kit process via a heap out-of-bounds write, resulting in Denial of Service. Affected deployments span Red Hat Enterprise Linux 6 through 10, Red Hat Hardened Images, and OpenShift Container Platform 4. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
SELinux label manipulation via TOCTOU race condition in the policycoreutils fixfiles script allows a local low-privileged attacker to corrupt SELinux mandatory access control labels on arbitrary system files, including security-critical targets such as /etc/shadow. The flaw affects fixfiles when run in relabel or restore mode across all supported Red Hat Enterprise Linux releases (6 through 10), Red Hat Hardened Images, and OpenShift Container Platform 4. No public exploit code or active exploitation has been identified at time of analysis, and exploitation is constrained by both a required race condition win and the need for an administrator to actively invoke fixfiles.
Header injection in openshift/oauth-proxy allows unauthenticated network attackers to impersonate arbitrary users on upstream applications by exploiting authentication-bypass paths. When skip-auth-regex rules are configured, the proxy forwards client-controlled identity headers (X-Forwarded-User, X-Forwarded-Email, X-Forwarded-Access-Token) to upstream services without stripping them, enabling forged identity claims. Affecting Red Hat OpenShift Container Platform 4, this vulnerability is classified under CWE-345 (Insufficient Verification of Data Authenticity) with a CVSS 6.5 base score; no public exploit code or CISA KEV listing has been identified at time of analysis.
Prometheus metric label cardinality exhaustion in Red Hat Build of Keycloak allows any authenticated user to crash the service by flooding its metric store with unique entries. When the Keycloak metrics subsystem is active, failed account operations (such as login attempts referencing nonexistent client IDs) cause raw, unsanitized error strings to be registered as Prometheus label values; because Prometheus stores each unique label combination as a distinct time series, a low-privileged attacker can generate an unbounded number of distinct metric entries, consuming JVM heap until the process crashes or becomes unresponsive. No public exploit code and no CISA KEV listing exist at time of analysis, but the low attack complexity and broad authenticated-user surface make this a realistic denial-of-service risk in any deployment where metrics are enabled.
Keycloak's LDAP storage provider allows delegated administrators to bypass configured search boundaries by supplying a crafted Distinguished Name (DN), exposing account information from unauthorized directory subtrees and triggering unintended user imports into Keycloak local storage. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, Red Hat Data Grid 8, and the JBoss EAP Expansion Pack. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; exploitation is constrained to authenticated delegated administrators with access to the LDAP federation interface.
Persistent denial of service in libkcapi's AIO interface allows a local attacker to permanently hang an affected application thread by exploiting improper error-state handling in _kcapi_aio_read_all(). Affected deployments span Red Hat Enterprise Linux 8, 9, and 10, Red Hat Hardened Images, and Red Hat OpenShift Container Platform 4 - all environments where applications leverage libkcapi's asynchronous cryptographic operations. No public exploit code or active exploitation has been identified at time of analysis; the high attack complexity (AC:H) and local-only attack vector substantially limit real-world risk beyond targeted or insider-threat scenarios.
IV reuse in libkcapi's one-shot symmetric cipher operations allows a remote attacker to weaken data confidentiality for applications processing inputs larger than 64 KiB under stateful modes (CTR or CBC). Affected deployments include Red Hat Enterprise Linux 8, 9, and 10, Red Hat Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation has been identified; the AV:N vector reflects an indirect attack path where an adversary induces a vulnerable application to process specially crafted oversized inputs, enabling ciphertext analysis to expose plaintext relationships or recover data.
Persistent denial of service in dhcp-server (dhcpd) on Red Hat Enterprise Linux 6 through 9 is triggered via a crafted OMAPI lease creation request containing an overly long InfiniBand MAC address, overflowing a buffer in `print_hw_addr()` and crashing the dhcpd daemon in a way that prevents automatic recovery. The official CVSS score of 4.9 with PR:H reflects the assumption that TSIG authentication guards the OMAPI port; however, the description explicitly highlights that TSIG is optional and often absent, reducing the realistic exploitation barrier to unauthenticated network access. No confirmed active exploitation (KEV) or public proof-of-concept exists at time of analysis.
Stack-based out-of-bounds read in stunnel's s_vlog logging function allows remote unauthenticated attackers to crash the service by sending protocol inputs that generate log messages exceeding 1024 bytes via vsnprintf. The primary impact is service disruption (availability), with a limited integrity impact in corner cases where trailing newline characters in the stack buffer can be overwritten with null bytes. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
SSRF bypass in stunnel 5.79 and earlier allows authenticated SOCKS proxy clients to circumvent intended localhost access restrictions by supplying IPv4-mapped IPv6 addresses (e.g., ::ffff:127.0.0.1) or unspecified addresses (0.0.0.0, ::) in proxy requests. Exploitation reaches loopback-bound services on the stunnel host - services deliberately isolated from external network access - potentially exposing internal APIs, administrative interfaces, or other localhost-only endpoints. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog at time of analysis.
Off-by-one memory corruption in popt's poptStuffArgs function allows a local low-privileged attacker to overwrite adjacent memory and potentially execute arbitrary code within any host application that unsafely processes the corrupted argument data. All supported Red Hat Enterprise Linux releases (6 through 10), Red Hat Hardened Images, and OpenShift Container Platform 4 ship the affected library. No public exploit code has been identified and no CISA KEV listing exists; exploitation requires high-complexity triggering conditions, making this a routine patch priority rather than an emergency response item.
Uninitialized heap memory disclosure in SSSD's NSS responder exposes cached directory data and heap layout to local authenticated users on RHEL 6 through 10 and OpenShift Container Platform 4. The sss_nss_protocol_fill_initgr() function pre-allocates a reply buffer sized for all group entries but fails to shrink it when groups are skipped, causing uninitialized heap bytes to be included in the response transmitted back to the requesting client. No public exploit code has been identified at time of analysis, and this is not listed in CISA KEV; however, leaked heap addresses may assist in chained attacks targeting ASLR bypass in sssd_nss.
Forced logout via unsigned backchannel requests affects Red Hat Build of Keycloak when an OIDC identity provider is configured to skip signature validation. Under this non-default configuration, the backchannel logout endpoint in keycloak-services improperly accepts logout requests lacking any cryptographic signature (CWE-347), violating the OIDC backchannel logout specification. An unauthenticated network attacker who possesses knowledge of a target user's session identifiers can submit a forged unsigned logout request, terminating that session without the user's consent. No public exploit or active exploitation (CISA KEV) has been identified; with CVSS 3.7 and EPSS data absent from the input, this is a low-priority availability-only issue gated by a specific non-default configuration.
Path traversal in WildFly's domain mode LocalFileRepository exposes arbitrary files readable by the Domain Controller process to attackers who have already obtained or compromised a slave host controller. The flaw resides in the wildfly-core/deployment-repository component, where getFile() and getConfigurationFile() fail to canonicalize or bound-check caller-supplied paths before resolving them on disk, enabling directory traversal sequences to escape the configured repository root. No active exploitation is confirmed (not listed in CISA KEV) and no public exploit code has been identified, but successful exploitation yields high-confidence access to sensitive artifacts including keystores, credentials, and configuration files.
GNU tar's incremental restore path contains a TOCTOU race condition in dumpdir 'X' rename handling, allowing a local attacker with write access to a backed-up directory to redirect file operations outside the intended extraction root during a privileged restore. Successful exploitation can result in arbitrary file creation, rename, or overwrite - enabling privilege escalation on systems running Red Hat Enterprise Linux 6 through 10 and Red Hat Hardened Images. No public exploit is identified at time of analysis, and no CISA KEV listing exists; the CVSS score of 4.4 reflects the constrained attack prerequisites including a required race window and administrator-initiated restore.
Authentication bypass in 389 Directory Server (Red Hat Directory Server 11-13) allows a network-connected user holding valid credentials for an administratively locked account to retain an authenticated LDAP session, defeating account-lock as an access-revocation control. The SASL PLAIN bind handler installs connection-level authenticated state before executing the account-lock check; when the lock check fails, only the error is returned to the client while the internal authenticated state on that connection persists unrevertd. No public exploit has been identified at time of analysis and no CISA KEV listing exists, but the real-world impact is highest in incident-response and employee-offboarding scenarios that rely on directory lock as the primary revocation mechanism.
GNU tar's --one-top-level extraction mode fails to confine hardlink targets to the designated top-level directory, allowing a crafted archive to plant hardlinks that escape the intended extraction boundary. When combined with a preexisting symbolic link already present under the working directory, an attacker who can induce a victim to extract a malicious archive may read or write files outside the intended extraction scope on systems running affected RHEL versions (6 through 10) and Red Hat Hardened Images. No public exploit has been identified at time of analysis, and exploitation requires both user interaction and a specific environmental pre-condition, keeping real-world risk moderate despite GNU tar's ubiquitous deployment.
Out-of-bounds read in SSSD's NSS responder allows a local user with standard privileges to crash the SSSD process by sending a crafted GETHOSTBYADDR request, causing system-wide denial of authentication and name resolution services. The vulnerable function `sss_nss_protocol_parse_addr()` fails to validate the `addrlen` field against the actual remaining packet body size, enabling heap over-read and process termination. No public exploit code or active exploitation has been identified at time of analysis, and this vulnerability is not listed in CISA KEV.
Heap-based out-of-bounds write in GIMP's PAA (Paint Shop Pro Array) file format plugin allows a remote attacker to potentially execute arbitrary code on a victim's system by tricking the user into opening a specially crafted PAA image. The flaw resides in the decode_lzss() decompression function, which writes data beyond the bounds of the allocated heap buffer, enabling heap metadata corruption. No public exploit or CISA KEV listing exists at time of analysis, but the RCE-tagged impact and buffer-write primitive make this a higher-severity risk than the CVSS 5.5 score suggests; the CVSS impact metrics reflect only availability (A:H) while the description and tags indicate arbitrary code execution potential - a notable discrepancy to investigate.
Stack-based buffer overflow in GIMP's file-png plugin on Red Hat Enterprise Linux 6 through 9 causes the application to crash when a user opens a crafted Animated PNG (APNG) image containing an oversized tRNS chunk, resulting in a Denial of Service limited to the affected user session. Exploitation requires local file access and active user interaction - a remote attacker would rely on social engineering (phishing, malicious download) to deliver the file. No active exploitation has been confirmed by CISA KEV, no public exploit code is identified at time of analysis, and EPSS data is unavailable in source intelligence.
Client policy enforcement in Red Hat Build of Keycloak can be bypassed by an authenticated user holding client management permissions, allowing non-compliant OAuth clients to persist in a realm despite administrator-configured security hardening. The bypass exploits improper client state evaluation during update operations: an attacker creates a public client - which passes policy validation - and then updates it to a confidential client type, skipping the re-evaluation that would normally reject a non-compliant confidential client. No public exploit code has been identified and this CVE is not listed in CISA KEV; however, the low attack complexity and broad deployment of Keycloak in enterprise IAM infrastructure elevate its practical significance.
Time-based authorization policy bypass in Red Hat Build of Keycloak permits any low-privileged authenticated user to inject a fabricated timestamp into their authorization request, causing Keycloak's Authorization Services engine to evaluate the forged value instead of the actual server clock. This fully defeats time-based access controls - such as business-hours restrictions - across affected Red Hat products including Keycloak, Single Sign-On 7, Data Grid 8, and JBoss EAP Expansion Pack. No public exploit code has been identified and this CVE is not listed in CISA KEV, but the CVSS High integrity impact accurately reflects that time-gated authorization controls are rendered entirely ineffective against any valid account holder.
The full-scope-disabled client-policy executor in Red Hat Build of Keycloak silently skips enforcement when the fullScopeAllowed attribute is absent from a client registration or update request, allowing a delegated user to create OAuth/OIDC clients with unrestricted scope access. Affected platforms span Red Hat Build of Keycloak, Red Hat Single Sign-On 7, Red Hat Data Grid 8, and JBoss EAP Expansion Pack. An attacker holding delegated registration privileges (CVSS PR:L) can exploit this to issue tokens containing unauthorized role mappings, effectively escalating their effective permissions within any application trusting those tokens. No public exploit code or CISA KEV entry has been identified at time of analysis.
Incomplete HTTP parameter pollution validation in Keycloak's keycloak-services component exposes OIDC authentication flows to session fixation and account confusion attacks. The security check inspects only the query string of redirect URLs while ignoring the URL fragment, enabling an attacker to inject duplicate security parameters when a client is configured with a wildcard redirect URI. No public exploit has been identified at time of analysis; the CVSS score of 3.4 (AC:H, UI:R) correctly reflects that exploitation requires both a permissive wildcard redirect URI configuration and a non-spec-compliant client application that trusts attacker-injected parameters over Keycloak-issued values.
Wildcard domain validation in Keycloak's keycloak-services component can be bypassed by an attacker who controls their connection's reverse DNS, enabling unauthorized client registration or modification against a Keycloak realm. The flaw stems from the system accepting any hostname that merely ends with the configured domain suffix (e.g., 'attackerexample.com' satisfying a '*.example.com' restriction) rather than enforcing true subdomain membership. Exploitation requires high attack complexity due to the reverse DNS control prerequisite, and no public exploit or CISA KEV listing has been identified at the time of analysis.
Incorrect authorization in Keycloak's group policy evaluation allows a low-privileged authenticated user to bypass group membership checks and gain unauthorized access to administrative functions or protected resources. The root cause is a string prefix comparison used to verify child-group membership under an 'extend to child groups' policy: a user in a group whose name shares a leading prefix with a privileged group (e.g., '/admins-external' matching a policy scoped to '/admins') is incorrectly treated as a legitimate child-group member. The CVSS vector (PR:L, I:H) confirms this is an authenticated integrity-bypass with high impact. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Redirect URI policy bypass in Keycloak's secure-client-uris executor enables interception of OAuth authorization codes over unencrypted HTTP connections. The flaw exists because the executor performs only a prefix-string comparison on the redirect URI rather than properly parsing and validating the host component, allowing a specially crafted domain name to satisfy the HTTPS enforcement check while pointing to an attacker-controlled HTTP endpoint. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, and related Red Hat middleware products. No public exploit code or CISA KEV listing has been identified at time of analysis.
Keycloak's OIDC token introspection endpoint incorrectly discloses the full set of JWT claims to confidential clients inspecting tokens that were not issued for them. Any confidential client configured to receive signed JWT introspection responses can submit a foreign token, receive an 'inactive' status confirmation, and simultaneously receive the complete signed JWT payload containing sensitive user attributes and claims - effectively bypassing the audience isolation that OIDC introspection is designed to enforce. No active exploitation has been confirmed (not listed in CISA KEV), and no public proof-of-concept code has been identified at time of analysis, but the low attack complexity and network accessibility via a standard API endpoint make this a meaningful confidentiality risk in multi-tenant or multi-client Keycloak deployments.
Broken access control in Keycloak's RoleContainerResource component allows delegated administrators with manage-realm permissions to remove child roles from built-in admin roles via name-based endpoints in the admin REST API that skip proper authorization checks. Affected distributions include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, Red Hat JBoss EAP Expansion Pack, and Red Hat Data Grid 8. An attacker exploiting this flaw can degrade or disrupt administrative functions within a realm by stripping essential role assignments from built-in admin roles, effectively undermining the role-based access control structure of the affected deployment. No public exploit code and no CISA KEV listing are associated with this CVE at time of analysis.
SAML HTTP-Redirect binding in Keycloak allows network-based attackers to inject malicious parameters into authentication requests targeting clients configured with wildcard redirect URLs. When a victim user completes authentication, Keycloak appends its legitimate SAML response to the attacker-controlled URL parameters, which can cause susceptible service providers to process the attacker's data instead of the real login assertion - potentially resulting in the victim being logged into the wrong account. No public exploit is identified at time of analysis, and the CVSS score of 3.4 (Low) reflects the high attack complexity and limited integrity-only impact.
Token revocation bypass in Keycloak's TokenManager component allows sessions and user data access to persist after administrative invalidation. The flaw (CWE-862: Missing Authorization) causes client-level 'not-before' revocation policies to be silently skipped when a realm-level revocation policy with an older, non-zero timestamp is already in place - causing the revocation to produce no effect. Authenticated token holders (PR:L) can continue refreshing sessions and querying user information APIs despite explicit administrative revocation. No public exploit identified at time of analysis; KEV status is not confirmed.
Insecure file permissions in ansible-collection-redhat-leapp expose PostgreSQL backup archives to local non-root users on managed RHEL 9 and RHEL 10 nodes. When the `leapp_old_postgresql_data` remediation option is invoked with elevated privileges, the resulting backup archive is written with world-readable or group-readable permissions (CWE-732), allowing any local non-root user on that managed node to extract the full contents of the archived PostgreSQL data. No public exploit has been identified at time of analysis, and exploitation requires local authenticated access to the managed node.
The ansible-collection-redhat-leapp package exposes Ansible controller-side sensitive files to attacker-controlled managed nodes through a manipulated Leapp upgrade report. An attacker who has already obtained privileged write access to a managed node's Leapp report can craft malicious report content that, when an operator executes a specific remediation task, causes the Ansible controller to read and copy its own local files - including private keys and credentials - to the attacker-controlled managed node. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the CVSS 3.1 score of 6.2 reflects real-world risk limited by the high privilege prerequisite and required operator interaction.
Denial of service in Samba's Kerberos KDC password change (kpasswd) service allows authenticated remote attackers to crash the KDC process by submitting specially crafted, malformed ASN.1-encoded password change requests. The server miscalculates the structure size of the incoming request and reads up to six bytes beyond the end of the allocated buffer; when this read strikes unmapped memory, the KDC process terminates rather than simply failing gracefully. No public exploit has been identified and no CISA KEV listing exists, but the disruption of a KDC in an Active Directory or Samba domain environment carries significant operational impact since authentication for the entire domain depends on KDC availability.
Samba's internal DNS server inserts unauthenticated TKEY registration requests into the TKEY name cache before rejecting them, allowing a remote unauthenticated attacker to exhaust the cache by flooding it with arbitrary TKEY names. Eviction of legitimate cache entries blocks TSIG-authenticated DNS query processing, producing a targeted denial of service against Active Directory environments relying on Samba's built-in DNS backend. No public exploit code or CISA KEV listing has been identified at time of analysis; a vendor patch is available from both Samba upstream and Red Hat.
Server-side request forgery in Dogtag PKI's ACME responder enables unauthenticated ACME account holders to direct the certificate server to make arbitrary HTTP GET requests to internal network addresses. The validator incorrectly accepts IP address literals as valid DNS identifiers and follows HTTP redirects without enforcing RFC-compliant public-address filtering, allowing internal network reconnaissance. When the InMemory database backend is in use, the response body returned by internal services is exposed to the attacker through ACME challenge error messages, compounding the confidentiality impact. No public exploit code or active exploitation has been identified at time of analysis.
Path traversal in the Performance Co-Pilot (PCP) pmproxy logger servlet on Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4 permits unauthenticated remote attackers to create arbitrary files and directories on the host filesystem by supplying a crafted hostname value in requests to the service. The primitive is write-only - no file contents can be read - but an attacker can abuse it to corrupt directory structures or exhaust disk space, leading to denial of service. No public exploit code has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog.
Remote unauthenticated denial of service and memory disclosure in the Performance Co-Pilot (PCP) pmproxy service affects Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. An out-of-bounds read (CWE-125) in the pmLogLoadInDom() function can be triggered by a specially crafted network request, causing the pmproxy process to crash and potentially leaking sensitive data from process memory. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Missing authorization in Keycloak's administrative API allows a scoped administrator to exceed their privilege boundary by linking identity providers to organizations they are not authorized to manage. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, and related Red Hat products. An administrator who holds identity provider management permissions but lacks organization management rights can silently reconfigure authentication flows for organizations outside their administrative scope, potentially redirecting user logins through attacker-controlled providers. No public exploit code exists and this vulnerability is not listed in CISA KEV at time of analysis.
Client policy enforcement in Keycloak is bypassable by any user holding client management privileges who exploits a group-name collision across the group hierarchy. Because the policy engine resolves group membership by display name rather than unique identifier, an attacker can create or join a group in a different part of the hierarchy that shares a name with a privileged policy group, then register or update OAuth/OIDC clients without satisfying the required security hardening profiles. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV.
Out-of-bounds heap read in GNU Binutils linker when processing 32-bit XCOFF files allows local attackers to disclose heap memory and cause denial of service. Affects Red Hat Enterprise Linux 6 through 10, Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation identified at time of analysis; EPSS data unavailable.
Authorization bypass in Red Hat Certificate System's CA renewal path allows an authenticated user to renew a certificate belonging to a different realm without the required realm-based authorization check. Affects versions 9, 10, and 11 of the Certificate System on Red Hat Enterprise Linux 6 through 10. No evidence of active exploitation or public exploit code exists at the time of analysis, and EPSS probability is low (0.21%).
Information disclosure in Red Hat Build of Keycloak allows restricted administrators to view private user details (names, email addresses) via the role-users endpoint, due to a missing permission check. The flaw affects the keycloak-services library, exposing sensitive data to low-privilege users. No active exploitation or public exploit is known, and EPSS indicates low exploitation probability.
Information disclosure in the Keycloak Admin REST API allows a delegated administrator with view-only permissions to retrieve the resolved client secret from a secure vault instead of the vault placeholder, exposing sensitive credentials. Affected Red Hat builds include Keycloak, Single Sign-On 7, Data Grid 8, and JBoss EAP expansion pack. No active exploitation or public exploit is known; EPSS probability is low (0.21%).
Local information disclosure in accountsservice on Red Hat Enterprise Linux allows systemd-homed users to read arbitrary files via the SetIconFile handler. A proof-of-concept exists, but exploitation requires a local account managed by systemd-homed, limiting impact
Denial of service in dbus-broker allows a local attacker to crash the user session bus broker when file descriptor limits are exhausted. Affected products include Red Hat Enterprise Linux 9/10, Red Hat OpenShift Container Platform 4, and Red Hat Hardened Images where dbus-broker is deployed. No active exploitation or public exploit code is known, and EPSS indicates low exploitation probability (0.11%).
Server-Side Request Forgery (SSRF) in Red Hat Quay 3's notification webhook feature allows repository administrators to weaponize the Quay worker process as an internal network proxy. By supplying attacker-controlled URLs to the Slack or generic webhook notification handlers, a repository admin can cause the Quay backend to issue POST requests to RFC-1918 addresses, cloud metadata endpoints (e.g., AWS IMDSv1 at 169.254.169.254), or other infrastructure that should be network-isolated from the application. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
Red Hat Certificate System (RHCS) 9 is susceptible to a resource exhaustion denial-of-service condition triggered by unauthenticated remote attackers flooding its TLS-exposed HTTP endpoint. Repeated requests cause the underlying Java process to exhaust available heap memory, resulting in an Out of Memory crash that takes the certificate authority service offline. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity and absence of authentication requirements make this a realistic threat to any internet- or intranet-exposed RHCS deployment.
Out-of-bounds heap read in gdk-pixbuf's ICO parser exposes heap memory content through rendered image output, affecting Red Hat Enterprise Linux 6 through 10. When processing a crafted ICO file whose pixel indices exceed the defined palette size, the library reads beyond the palette array boundary - heap bytes are treated as palette entries and rendered as RGB pixel values in the output image, enabling an attacker to extract heap content by analyzing the rendered result. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but server-side image processing pipelines that return rendered output to untrusted callers represent a realistic exposure path.
Format string vulnerability in GNU nano's multi-buffer error message handling allows a local low-privileged attacker to cause stack information disclosure, denial of service via crash, or potentially achieve arbitrary memory writes. The flaw (CWE-134) is triggered when a user opens multiple files at startup, one of which carries a specially crafted name containing printf format specifiers and another triggers an ALERT-level error - causing nano to misinterpret the filename as a format string. Reported by Red Hat and scoped to RHEL 6 through 10 and OpenShift Container Platform 4, no public exploit or CISA KEV listing exists at time of analysis.
PKCE bypass in librest allows OAuth 2.0 client impersonation by exploiting a cryptographically weak pseudo-random number generator. The library's code verifier generation for PKCE (RFC 7636) uses GLib's GRand function - a non-cryptographic PRNG with a 32-bit seed space - rather than a CSPRNG, enabling a positioned attacker to recover the PRNG seed and reconstruct the code verifier to hijack the token exchange. Rated CVSS 6.8 with high confidentiality and integrity impact; no public exploit or CISA KEV listing identified at time of analysis.
Symlink-following vulnerability (CWE-59) in systemd-tmpfiles allows a local, low-privileged user to redirect privileged file write operations to an attacker-controlled path on affected Red Hat Enterprise Linux systems. The flaw resides in the path resolution logic within chase.c, where a safety check incorrectly treats all transitions away from the root user as inherently safe - failing to detect attacker-placed symlinks at tmpfiles.d target path components. Exploitation is constrained by high attack complexity requiring a specific non-default tmpfiles.d configuration, and no public exploit code or CISA KEV listing has been identified at time of analysis.
Heap buffer overflow in Red Hat Directory Server (389-ds-base) exposes LDAP services to remote unauthenticated denial of service or potential arbitrary memory write via malformed DN input. When a Distinguished Name containing a legacy-quoted value is processed, the server fails to close the associated heap allocation, permitting a subsequent operation to reference the same memory pointer - a classic heap confusion primitive. No public exploit has been identified at time of analysis, and this vulnerability is not listed in CISA KEV, though the network-accessible unauthenticated attack surface warrants prompt patching for any externally reachable Directory Server deployment.
