Linux kernel rxrpc subsystem allows remote denial of service via malformed RESP challenge packets due to incorrect serial number comparison logic. The rxrpc_post_response() function compares challenge serial numbers from the wrong packet structure, causing response queue corruption that can crash the kernel networking stack. This affects Linux kernel versions containing commit 5800b1cf3fd8 through the 6.16-6.19 and 7.0 series. Patches are available from kernel.org for affected stable branches. EPSS exploitation probability is very low (0.02%, 4th percentile) and no public exploits or active exploitation have been identified, suggesting limited real-world risk despite the network-accessible attack vector.
Out-of-bounds read in Linux kernel's rxrpc rxgk authentication handler allows remote unauthenticated attackers to trigger information disclosure and denial of service via malformed RESPONSE authenticator packets. The vulnerability stems from incorrect pointer arithmetic in rxgk_verify_authenticator() that inflates the parser boundary check by a factor of four, allowing reads beyond kmalloc() buffer boundaries. Vendor patches available for kernel versions 6.18.23, 6.19.13, and 7.0. EPSS score of 0.02% (4th percentile) suggests low observed exploitation probability despite network attack vector, though KASAN reports confirm reproducibility.
A double-free vulnerability in the Linux kernel's SMB Direct (RDMA transport) server implementation allows remote unauthenticated attackers to trigger memory corruption with high CVSS 9.8 severity. The flaw occurs when smb_direct_free_sendmsg() is called twice on the same memory region after smb_direct_flush_send_list() moves messages to a batch list. Vendor patches available across kernel versions 6.18.24, 6.19.14, and 7.0.1, with upstream commits confirmed in stable branches. Despite critical CVSS scoring, EPSS probability remains very low at 0.02% (4th percentile) and no active exploitation or public POC identified, suggesting limited real-world targeting of this SMB Direct RDMA feature.
Use-after-free in Linux kernel MediaTek video encoder allows local authenticated users to corrupt memory and potentially execute arbitrary code. The flaw affects the vcodec driver's encoder release path where ctx memory is freed before canceling scheduled workqueue tasks, enabling race conditions between cleanup and worker threads that may dereference freed memory. KASAN-confirmed exploitation requires local access with low privileges (CVSS AV:L/PR:L). Patches available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS score of 0.02% (5th percentile) indicates very low probability of automated exploitation, with no public exploit identified at time of analysis.
Out-of-bounds memory access in Linux Kernel's KVM subsystem for LoongArch architecture allows local authenticated attackers with low privileges to read limited kernel memory and cause system crashes. The vulnerability stems from improper handling of empty EIOINTC coremap values in eiointc_update_sw_coremap(), resulting in invalid array indexing into kvm_arch::phyid_map::phys_map[]. While CVSS rates this 7.3 HIGH, the EPSS score of 0.02% (4th percentile) indicates minimal real-world exploitation activity. No active exploitation (not in CISA KEV) or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.18.21, 6.19.11, 7.0, and mainline).
Out-of-bounds array access in Linux kernel KVM subsystem on LoongArch allows local authenticated attackers with low privileges to execute arbitrary code, escalate privileges, or cause denial of service by passing negative cpuid values to kvm_get_vcpu_by_cpuid(). The function lacks bounds checking before indexing phyid_map::phys_map[], enabling read/write beyond array boundaries with container escape potential (CVSS scope change). Vendor patches available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11). EPSS score of 0.02% indicates low automated exploitation likelihood, with no confirmed active exploitation or public POC at time of analysis.
Address calculation error in Linux kernel KVM on ARM64 allows local authenticated attackers with low privileges to corrupt memory descriptors, potentially enabling container escape or privilege escalation to compromise host integrity and confidentiality. The vulnerability affects KVM's stage-1/stage-2 page table descriptor swapping logic where pointer arithmetic incorrectly multiplies the offset by 8, causing writes to unintended memory locations. Vendor patches available for Linux 6.19.11 and mainline with EPSS exploitation probability at 5th percentile, indicating low observed exploitation despite high CVSS severity.
Denial of service via CPU soft lockup in Linux kernel's wlcore Wi-Fi driver (versions 5.10 through 7.0) occurs when memory allocation fails during wireless frame transmission. Incorrect error code return (-EAGAIN instead of -ENOMEM) triggers infinite retry loop while holding critical mutex, causing system unresponsiveness. Vendor-released patches available across all affected stable kernel branches (5.10.253, 5.15.203, 6.1.167, 6.6.130, 6.12.78, 6.18.20, 6.19.10, 7.0). CVSS 7.5 (High) reflects network attack vector with no authentication required, though EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. No active exploitation confirmed (not in CISA KEV); no public exploit identified at time of analysis.
Use-after-free in Linux kernel tracing subsystem allows local authenticated attackers to achieve arbitrary code execution, privilege escalation, or denial of service. The vulnerability occurs when deleting tracing instances with copy_trace_marker enabled, where improper RCU synchronization leaves freed memory accessible. Exploitation requires local access with low privileges to manipulate kernel tracing facilities. EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability. Vendor patches available across multiple stable kernel versions (6.18.20, 6.19.10, 7.0).
Denial of service in Linux kernel SMB server (ksmbd) affects versions 6.18 through 7.0-rc via race condition in SMBDirect receive credit management. Remote unauthenticated attackers can trigger resource exhaustion through crafted SMB packets exploiting the window between hardware reception and completion processing. Vendor patches released for stable branches 6.18.11, 6.19.1, and mainline 7.0. Low EPSS score (0.02%) indicates limited exploitation interest despite network attack vector and no authentication requirement.
Use-after-free in Linux kernel SMB server (ksmbd) RDMA handling allows remote unauthenticated attackers to execute arbitrary code, escalate privileges, or crash the system via crafted SMB Direct connections. The vulnerability arises when batched RDMA send operations without IB_SEND_SIGNALED flags are prematurely freed during connection failures, causing memory corruption. Vendor patches are available for kernel versions 6.18.11, 6.19.1, and 7.0. EPSS score of 0.02% suggests low observed exploitation probability, and no active exploitation or public POC is confirmed at time of analysis, though the critical CVSS score (9.8) reflects severe potential impact if the SMB Direct feature is enabled.
A type assertion bug in Kyverno's forEach mutation handler crashes the cluster-wide background controller into CrashLoopBackOff and blocks admission controller operations, causing denial of service for policy-matched resources. Any authenticated user with Policy or ClusterPolicy creation permissions can trigger the crash by creating a malformed policy. The vulnerability affects Kyverno versions prior to 1.17.2 and 1.16.4, is limited to the legacy policy engine (CEL-based policies unaffected), and persists until the malicious policy is deleted. Vendor-released patches available with confirmed fix commits on GitHub.
Kyverno's apiCall feature automatically attaches the admission controller's ServiceAccount token to HTTP requests without validating the destination URL, enabling authenticated attackers to exfiltrate tokens to attacker-controlled servers and achieve full cluster compromise through webhook configuration tampering. Affects Kyverno versions prior to 1.18.0-rc1, 1.17.2-rc1, and 1.16.4. Vendor-released patches available across all three affected version branches. EPSS data not provided, but the vulnerability enables privilege escalation from low-privilege Kubernetes user to cluster admin via token theft, representing critical risk in multi-tenant environments.
Cross-namespace privilege escalation in Kyverno 1.17.x allows authenticated namespace administrators to bypass RBAC controls and read ConfigMaps from any Kubernetes namespace. The vulnerability exploits unvalidated `configMap.namespace` field in Kyverno's ConfigMap context loader, enabling attackers to leverage Kyverno's privileged service account permissions. This is a regression following incomplete fix for CVE-2026-22039, which addressed the same issue in `apiCall` context but missed the ConfigMap loader. Patch available in version 1.17.2. CVSS 7.7 with Changed Scope indicates significant multi-tenant cluster risk; EPSS data not available but the regression nature and RBAC bypass impact warrant immediate patching in multi-tenant environments.
Lua code injection in Contour (Kubernetes ingress controller for Envoy) from v1.19.0 through the fixes in v1.31.6/v1.32.5/v1.33.4 lets a low-privileged tenant achieve arbitrary code execution inside the shared Envoy proxy. A user with RBAC rights to create or modify HTTPProxy resources injects Lua via the cookie-rewrite pathRewrite.value field; although the code only runs on the attacker's own route, it executes in shared infrastructure and can steal Envoy's xDS credentials (exposing other tenants' TLS keys) or cause denial of service for co-tenants. No public exploit identified at time of analysis, and EPSS is low (0.07%, 22nd percentile), consistent with the requirement for pre-existing cluster RBAC access.
Denial of service in the Argo Workflows controller (versions 3.6.5 through 4.0.4, plus the 3.7.0-rc1 through 3.7.12 pre-releases) lets any user able to submit a workflow crash-loop the entire controller by attaching a malformed workflows.argoproj.io/pod-gc-strategy pod annotation that contains no '/' separator, triggering an out-of-range index panic in an informer goroutine that sits outside the controller's recover() scope. Because the poisoned pod persists across restarts, the controller enters CrashLoopBackOff and halts all workflow processing cluster-wide until the pod is manually deleted. A working proof-of-concept manifest is published in the GHSA advisory (SSVC exploitation status: poc), but there is no evidence of active exploitation and EPSS is very low at 0.04%.
Command injection in radare2 PDB parser (versions before 6.1.4) enables arbitrary OS command execution when users analyze malicious PDB files. Publicly available exploit code exists. Attackers craft PDB files with newline characters in symbol names to inject radare2 commands during flag renaming operations, which then execute OS commands via radare2's shell operator when victims run the 'idp' command. CVSS 8.4 reflects local attack vector requiring user interaction, though EPSS data not available. Patch released in version 6.1.4 with detailed technical disclosure at blog.calif.io showing 0-day discovery process.
Memory corruption in rust-openssl's key derivation functions allows heap or stack buffer overflow when applications pass undersized buffers to Deriver::derive or PkeyCtxRef::derive on OpenSSL 1.1.x. The vulnerability affects X25519, X448, DH, and HKDF-extract operations where OpenSSL ignores the caller-specified buffer length and unconditionally writes the full shared secret, causing safe Rust code to trigger memory corruption. Vendor patch available in v0.10.78; OpenSSL 3.x deployments are not affected as newer providers correctly validate buffer lengths.
Out-of-bounds memory write in rust-openssl's AES key unwrap function allows attackers who control buffer sizes to corrupt memory via safe API misuse. The aes::unwrap_key() function contains an inverted bounds assertion that accepts undersized output buffers and rejects correctly sized ones, causing the function to write beyond allocated memory by in_.len() - 8 - out.len() bytes. Vendor patch available via GitHub PR #2604 and commit 718d07ff, released in openssl-v0.10.78. No evidence of active exploitation (not in CISA KEV) or public proof-of-concept at time of analysis, but the logic flaw is clearly documented in vendor advisory GHSA-8c75-8mhr-p7r9.
Stack-based buffer overflow in rust-openssl's MdCtxRef::digest_final() allows safe Rust code to corrupt memory when EVP_DigestFinal() writes beyond the provided output buffer boundary. The vulnerability occurs when the output buffer is smaller than EVP_MD_CTX_size(ctx), causing EVP_DigestFinal() to write past the buffer end and corrupt stack memory. Vendor-released patch available in version 0.10.78 via GitHub commit 826c3888. No public exploit identified at time of analysis, but exploitable from memory-safe Rust code paths, violating Rust's safety guarantees.
Server-side request forgery in monetr's Lunch Flow integration allows authenticated users on self-hosted instances to force the server to issue HTTP GET requests to arbitrary URLs, with response bodies from failed requests reflected in API error messages. This enables information disclosure attacks against internal networks, cloud metadata endpoints (AWS EC2 instance metadata without IMDSv2), and RFC1918 private addresses. The vulnerability is compounded by unbounded response buffering that creates a denial-of-service vector via memory exhaustion. Patch available in v1.12.5. The hosted my.monetr.app service is not affected as Lunch Flow is disabled there. Self-hosted instances with default configuration (Lunch Flow enabled, public signup allowed) are at highest risk.
SQL injection in Daptin's `/aggregate/:typename` endpoint allows authenticated low-privilege users to extract arbitrary database content via unsanitized query parameters. The `column` and `group` parameters are passed directly to raw SQL literal expressions without validation, enabling data exfiltration from any table including user credentials, database schema disclosure, and cross-table correlation attacks. Patched in version 0.11.4 which replaces all raw SQL construction with parameterized queries and schema-based validation. No evidence of active exploitation or public POC at time of analysis, though exploitation is straightforward for authenticated users.
Complete authentication bypass in openvpn-auth-oauth2 plugin mode (v1.26.3-1.27.2) grants VPN access to unauthenticated clients. Legacy OpenVPN clients lacking WebAuth/SSO support bypass OIDC authentication entirely and gain full network access due to incorrect plugin return codes. Only the experimental shared-library plugin deployment is affected; the default management-interface mode is not vulnerable. Vendor patch released in v1.27.3 with confirmed fix commits. No active exploitation reported, but trivial to exploit with standard Linux openvpn CLI against vulnerable deployments.
Remote attackers can corrupt PowerDNS Authoritative Server configuration via specially crafted DNS NOTIFY requests, causing persistent denial of service requiring manual administrator intervention. The attack adds malformed secondary domains to the bind backend, rendering the configuration invalid and preventing the server from restarting. No active exploitation confirmed at time of analysis, but the network-accessible attack vector and lack of authentication requirements elevate risk for internet-facing authoritative DNS servers.
Remote denial of service in dnsdist allows unauthenticated attackers to crash the DNS load balancer by sending specially crafted DNSCrypt queries that trigger a divide-by-zero error. The vulnerability requires no authentication, low attack complexity, and directly impacts service availability for all DNS traffic routed through affected dnsdist instances. Organizations using DNSCrypt protocol support in dnsdist face immediate risk of service disruption from remote attackers.
Use-after-free in Linux kernel CXL (Compute Express Link) subsystem allows local authenticated attackers to corrupt memory and potentially execute arbitrary code or cause kernel panics. The flaw occurs in cxl_detach_ep() during device removal when parent port references are freed prematurely, before child operations complete. Affects Linux kernel 6.3 through 7.0-rc5; patched in versions 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% indicates low exploitation probability. No active exploitation or public exploit code identified at time of analysis.
Double-free memory corruption in Linux kernel bcmasp network driver allows local authenticated attackers with low privileges to achieve arbitrary code execution, privilege escalation, or system crash. The vulnerability affects kernel versions 6.6 through early 7.0 release candidates. Vendor patches available across stable branches (6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (5th percentile) indicates very low real-world exploitation probability, and no active exploitation or public POC has been identified. This represents a low-priority issue for most environments despite the 7.8 CVSS score, as it requires local authenticated access and affects only systems using the specific bcmasp Broadcom network driver.
Use-after-free in Linux kernel RDMA/EFA driver allows local authenticated users with low privileges to execute arbitrary code with high confidentiality, integrity, and availability impact. The vulnerability affects the admin queue completion handling where completion context data is accessed after being freed, creating a window for memory corruption exploitation. Affects kernel versions from 5.12 through 7.0-rc7, with vendor patches available for stable branches 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability, and no public exploit code or CISA KEV listing identified at time of analysis.
Use-after-free in Linux kernel's xe GPU driver allows local authenticated users to execute arbitrary code with kernel privileges. The vulnerability occurs in the SR-IOV physical function migration restore path when error handling fails to nullify a freed data pointer, enabling subsequent write operations to reference deallocated memory. With CVSS 7.8 (High) and very low EPSS (0.02%), this represents typical kernel memory corruption risk requiring local access and low privileges. Vendor patches are available for affected 6.19 and 7.0-rc versions.
Memory exhaustion and kernel crash in Linux kernel's ksmbd SMB server allows remote unauthenticated denial of service via crafted lock requests. The smb2_lock() function contains three critical error-handling defects: memory leaks when vfs_lock_file() returns unexpected errors, stale error propagation in UNLOCK operations, and NULL pointer dereference during rollback when smb_flock_init() allocation fails. CVSS vector indicates network-accessible, low-complexity exploitation requiring no authentication. EPSS score of 0.02% (7th percentile) suggests minimal observed scanning activity, and no KEV listing confirms no widespread exploitation detected. However, the network attack vector (AV:N) and high availability impact (A:H) make this a realistic DoS risk for systems running ksmbd. Vendor patches available across stable kernel series 5.15-6.19.
Memory corruption in the Linux kernel sma1307 ASoC driver allows local authenticated users to trigger a double-free condition leading to potential privilege escalation, denial of service, or information disclosure. The vulnerability stems from improper cleanup of device-managed memory allocations in error paths within the sma1307_setting_loaded() function, where devm_kzalloc()-allocated resources are incorrectly freed with kfree(), causing devres to later release the same memory a second time. Vendor patches are available across multiple stable kernel branches (6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability, and no active exploitation or public POC has been identified.
Out-of-bounds write in Linux kernel ksmbd allows authenticated remote attackers to cause memory corruption via crafted SMB2 compound requests combining QUERY_DIRECTORY and QUERY_INFO commands. The vulnerability arises when get_file_all_info() fails to validate OutputBufferLength against available buffer space before converting filenames to UTF-16, enabling buffer overflow beyond response buffer boundaries. With CVSS 8.8 (High) and network attack vector requiring only low privileges, this presents significant risk to systems running ksmbd SMB server. Vendor patches available across multiple kernel versions (5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS exploitation probability remains low at 0.01% (2nd percentile), and no public exploit or CISA KEV listing identified at time of analysis.
Authentication bypass in MinIO object storage allows remote attackers to write arbitrary objects to any bucket using only a valid access key, without the corresponding secret key or cryptographic signature. The vulnerability affects MinIO RELEASE.2023-05-18T00-05-36Z through RELEASE.2026-04-11T03-20-12Z. Attackers can impersonate any user with WRITE permissions by exploiting a logic flaw in the STREAMING-UNSIGNED-PAYLOAD-TRAILER code path that incorrectly validates credentials from query parameters while bypassing signature verification. Vendor-released patch available in RELEASE.2026-04-11T03-20-12Z (GitHub commit 76913a9f). No public exploit identified at time of analysis, but exploitation requires only knowledge of a valid access key and target bucket name.
Authentication bypass in MinIO RELEASE.2023-05-18T00-05-36Z through RELEASE.2026-04-11T03-20-12Z allows remote unauthenticated attackers to write arbitrary objects to any bucket by exploiting an unvalidated auth type in the Snowball auto-extract handler. Attackers need only a valid access key (including the default 'minioadmin') and can fabricate signatures without knowing the secret key. CVSS 8.8 reflects network-accessible, low-complexity exploitation with no authentication required (CVSS:4.0 PR:N). No public exploit identified at time of analysis, but exploitation requires only basic S3 API knowledge. Patched in RELEASE.2026-04-11T03-20-12Z per vendor advisory GHSA-9c4q-hq6p-c237.
Unauthenticated remote attackers can crash free5GC Policy Control Function (PCF) versions before 1.4.3 via repeated HTTP requests to the OAM endpoint over the Service-Based Interface. Each request leaks memory by registering duplicate CORS middleware in the Gin router handler chain, causing progressive memory exhaustion that prevents all User Equipment from establishing 5G sessions. Patched in version 1.4.3 via commit 599803b. EPSS data unavailable; not listed in CISA KEV. CVSS 7.5 High severity reflects network-accessible unauthenticated attack with high availability impact.
Authentication bypass in OAuth2 Proxy 7.5.0-7.15.1 allows remote unauthenticated attackers to access protected resources by exploiting path normalization discrepancies between the proxy and backend services. When deployments use skip_auth_routes or skip_auth_regex with broad wildcard patterns, attackers can inject '#' or '%23' (URL-encoded fragment delimiter) to match public allowlist rules while the upstream application serves sensitive endpoints. CVSS 8.2 (AV:N/AC:L/PR:N/UI:N) reflects network-based unauthenticated access; no public exploit identified at time of analysis. EPSS data not provided. Fixed in version 7.15.2 through conservative path normalization.
Authentication bypass in Oxia (oxia-db) metadata store and coordination system prior to 0.16.2 allows an attacker holding a valid OIDC/JWT token issued for a different service by the same identity provider to authenticate to Oxia. The OIDC provider unconditionally set SkipClientIDCheck: true in the go-oidc verifier, disabling library-level audience (aud) validation and breaking the audience/tenant isolation that OAuth2/OIDC relies on. There is no public exploit identified at time of analysis, EPSS is very low (0.05%), and CISA SSVC records no known exploitation, but the technical impact is rated total.
Sensitive information disclosure in Oxia (a metadata store and coordination system) prior to 0.16.2 causes the full OIDC bearer token to be written in plaintext to application logs at DEBUG level whenever authentication fails. Anyone able to read those logs - via a compromised or shared log aggregation pipeline or misconfigured log access controls - can harvest valid JWTs (header, payload, and signature) and replay them to impersonate legitimate users. No public exploit identified at time of analysis; EPSS is low at 0.05%, and CISA SSVC records exploitation status as none.
Denial-of-service in Oxia (metadata store and coordination system) versions <= 0.16.1 allows a remote unauthenticated client to crash the entire data server process by racing rapid KeepAlive/heartbeat requests against session expiry or closure. The flaw is a concurrency bug (send on closed channel panic, or deadlock when the buffer fills) triggerable without authentication over the network. No public exploit identified at time of analysis; EPSS is low (0.04%) and CISA SSVC rates exploitation as none, but the low attack complexity makes it a credible availability threat once patched.
Remote denial of service in Coturn TURN/STUN server allows unauthenticated attackers to crash ARM64 deployments with a single malformed UDP packet. The vulnerability triggers a fatal SIGBUS signal via misaligned memory access during STUN attribute parsing, requiring no authentication or special configuration. All ARM64 installations of Coturn prior to 4.10.0 are vulnerable to instant process termination. EPSS exploitation probability is not yet available as this is a newly disclosed CVE, but the attack complexity is low (AC:L) and requires no privileges (PR:N), making exploitation trivial once awareness spreads in attacker communities.
Local privilege escalation in CivetWeb v1.16 service allows authenticated users to execute arbitrary code with SYSTEM privileges via unquoted service path exploitation. The Windows service configuration lacks quotes around 'C:\Program Files\CivetWeb\CivetWeb.exe', enabling attackers to place malicious executables in directories scanned before the intended path (e.g., 'C:\Program.exe' or 'C:\Program Files\CivetWeb.exe'). No public exploit identified at time of analysis, though EPSS data not available. Patch available per vendor advisory from INCIBE.

Fixed in Firefox 150, this CWE-200 information disclosure flaw enables attackers to circumvent existing security controls via network-based vectors. Despite a CVSS base score of 7.5 (High), real-world exploitation risk appears limited: EPSS probability is only 0.02% (5th percentile), no public exploit code has been identified, and CISA SSVC framework rates it as non-exploited with partial technical impact, though automatable.
Integer overflow in OpenEXR's DWA compressor (versions 3.2.0-3.2.7, 3.3.0-3.3.9, 3.4.0-3.4.9) enables local attackers to trigger memory corruption when processing maliciously crafted EXR image files requiring user interaction. This vulnerability represents a missed instance of the same integer overflow pattern addressed in related CVEs 2026-34589, 34588, and 34544, occurring in `internal_dwa_compressor.h:1040` where width multiplication lacks proper size_t casting. Given the local attack vector requiring user interaction (CVSS AV:L/UI:A), real-world exploitation requires social engineering to trick users into opening weaponized EXR files, making this primarily a workstation-targeted threat in media production environments. No active exploitation or public POC identified at time of analysis.
Privilege escalation in Neko virtual browser (versions 3.0.0-3.0.10, 3.1.0-3.1.1) allows any authenticated user with low privileges to immediately gain full administrative control over the entire instance, including member management, room settings, broadcast control, and session termination. This complete instance compromise requires only network access and valid user credentials (CVSS 8.8, AV:N/AC:L/PR:L). While EPSS exploitation probability is low (0.12%, 31st percentile) and no active exploitation has been confirmed, the vulnerability is trivially exploitable by any authenticated user and classified as non-automatable but with total technical impact per SSVC. Vendor patches are available in versions 3.0.11 and 3.1.2.
Server-Side Request Forgery in Glances IP plugin allows authenticated attackers to force the monitoring application to send HTTP requests to arbitrary internal or external endpoints, with automatic credential leakage when public_username and public_password are configured. The vulnerability affects all versions prior to 4.5.4 and arises from insufficient validation of the public_api configuration parameter. EPSS exploitation probability is low (0.04%, 12th percentile), but SSVC framework confirms proof-of-concept availability and automatable exploitation with partial technical impact. Vendor patch released in version 4.5.4.
Cross-origin data exfiltration in Glances web server allows remote unauthenticated attackers to read sensitive system information (CPU, memory, processes, network stats) through the REST API endpoint /api/4/* via malicious websites exploiting permissive CORS policy. Affects all versions prior to 4.5.4. EPSS score of 0.06% (18th percentile) suggests low widespread exploitation probability despite proof-of-concept availability, though the network-accessible, unauthenticated attack vector (AV:N/PR:N) combined with high confidentiality impact (VC:H) makes this a priority for internet-exposed instances.
Buffer overflow in glibc's obsolete NIS authentication function allows remote attackers to compromise integrity and availability via spoofed UDP responses. Affects all glibc versions through 2.43, but exploitation requires the target application to actively use the deprecated nis_local_principal function (obsolete since glibc 2.26). EPSS score of 0.02% (5th percentile) indicates low real-world exploitation probability, consistent with the narrow attack surface of legacy NIS deployments. No active exploitation or public exploit code identified at time of analysis.
Disabled user accounts in Nginx UI versions before 2.3.4 retain full API access through previously issued JWT tokens for the entire token lifetime, allowing attackers with stolen credentials to maintain persistent access and create new accounts even after administrative remediation attempts. This authentication bypass enables continued confidentiality and integrity compromise of Nginx configurations despite account lockout. Reported by GitHub security advisories; no evidence of active exploitation (not in CISA KEV), but the token-reuse mechanism makes exploitation straightforward for attackers who have already obtained credentials.
Out-of-bounds read in the Linux kernel's X.509 certificate parser allows local unprivileged users to trigger memory corruption or denial of service by submitting a specially crafted certificate via the keyrings(7) API. The flaw exists in the handling of empty Basic Constraints or Key Usage extensions, where the first byte is dereferenced before the length check. A proof-of-concept was responsibly disclosed by the reporter, though no public exploit is identified at time of analysis and EPSS rates the exploitation probability as very low (0.01%).
Uncontrolled memory consumption in monetr 1.12.3 and earlier allows remote unauthenticated attackers to trigger denial of service by sending oversized payloads to the public Stripe webhook endpoint. The vulnerability affects deployments with Stripe webhooks enabled and lacks upstream body-size enforcement. Version 1.12.4 provides a fix. EPSS and KEV data not available; no public exploit confirmed at time of analysis, though the attack method is straightforward (8.2 CVSS reflecting high availability impact with low complexity).
Heap-based buffer overflow in xrdp 0.10.5 and earlier allows remote code execution after authentication via malicious EGFX graphics channel PDUs. Authenticated attackers can exploit insufficient validation of client-controlled size parameters to write beyond allocated heap buffers. Unauthenticated attackers can only trigger denial-of-service crashes. Vendor-released patch available in version 0.10.6. No active exploitation confirmed (not in CISA KEV), but heap overflows in remote services are high-value targets. Default non-privileged execution since 0.10.2 limits post-compromise impact.
Out-of-bounds read in xrdp 0.10.5 and earlier allows unauthenticated remote attackers to crash the RDP service or disclose memory contents during pre-authentication message parsing. The vulnerability (CWE-125) exploits insufficient buffer length validation in dynamic channel communication handling, affecting default installations exposed to network access. Fixed in version 0.10.6 per vendor advisory GHSA-92mr-6wpp-27jj. CVSS 8.7 reflects high availability impact; no active exploitation confirmed in CISA KEV at time of analysis, though public disclosure increases risk for internet-facing xrdp deployments.
Out-of-bounds read in xrdp RDP server versions ≤0.10.5 allows remote unauthenticated attackers to crash the service or disclose process memory by sending a malformed Confirm Active PDU during RDP capability negotiation. Attack complexity is low but requires user interaction. EPSS data not available; no CISA KEV listing or public POC identified at time of analysis. Vendor-released patch available in version 0.10.6 per GitHub security advisory GHSA-rvh9-9wm3-28c7.
Heap-based buffer overflow in xrdp's NeutrinoRDP module (versions ≤0.10.5) enables malicious downstream RDP servers or MitM attackers to achieve remote code execution or denial of service when proxying RDP sessions. Exploitation requires the victim xrdp server to have the non-default NeutrinoRDP module compiled and enabled (--enable-neutrinordp), and a user must initiate an RDP session through the affected proxy to a malicious server. EPSS data unavailable; no CISA KEV listing indicates targeted rather than widespread exploitation. Fixed in version 0.10.6.
Missing MAC signature verification in xrdp 0.10.5 and earlier allows man-in-the-middle attackers to modify encrypted RDP traffic without detection when Classic RDP Security layer is used. Unauthenticated network attackers with MITM position can alter packet contents in transit, achieving high integrity and confidentiality impact on both vulnerable and subsequent systems (CVSS 9.3, CVSS:4.0 with scope change). TLS security layer deployments are not affected. Vendor patch released in version 0.10.6. No active exploitation or public POC identified at time of analysis, but EPSS data unavailable for risk assessment.
Privilege escalation to root in xrdp 0.10.5 and earlier allows authenticated local attackers to execute arbitrary code due to improper error handling during privilege drop in the session execution component. The flaw requires low attack complexity and no user interaction (CVSS 8.8, AV:L/AC:L/PR:L/UI:N). Vendor-released patch available in xrdp v0.10.6. No public exploit or active exploitation confirmed at time of analysis, though CVSS scope change (S:C) indicates potential container/VM escape scenarios.
Remote code execution in Firebird RDBMS versions prior to 5.0.4, 4.0.7, and 3.0.14 allows authenticated users with CREATE FUNCTION privileges to execute arbitrary code as the database server process through path traversal in the external engine plugin loader. The vulnerability stems from insufficient input validation (CWE-22) when concatenating user-supplied engine names into filesystem paths, enabling attackers to load malicious shared libraries from arbitrary locations. With CVSS 10.0 and scope change (S:C), successful exploitation grants full system compromise beyond database boundaries. EPSS data not provided, no CISA KEV listing identified, indicating targeted rather than widespread exploitation at time of analysis. Vendor-released patches available across all affected major versions.
Firebird database server crashes via crafted slice packet exploiting zero-length SDL descriptor validation flaw. Remote unauthenticated attackers can trigger division-by-zero errors in the sdl_desc() function to cause denial of service against Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation with no authentication required. EPSS data not available; no public exploit identified at time of analysis, though technical details in GitHub advisory may facilitate reproduction.
Remote denial-of-service in Firebird Database Server versions prior to 5.0.4, 4.0.7, and 3.0.14 allows unauthenticated network attackers to crash the server via crafted XDR-encoded op_response packets. The xdr_status_vector() function fails to handle isc_arg_cstring status vector types during packet decoding, triggering immediate server termination. With CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) and CWE-228 (Improper Handling of Syntactically Invalid Structure), this represents a high-severity availability risk for internet-exposed Firebird instances. No active exploitation confirmed, but exploit development is trivial given the low attack complexity.
Buffer overflow in Firebird RDBMS allows remote unauthenticated attackers to crash database servers via malformed slice packets. Affects Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14 across all three maintained major release branches. The xdr_datum() deserialization function fails to validate cstring lengths against slice descriptor bounds during packet processing, enabling heap buffer overflow. CVSS 7.5 (High) with network attack vector and no authentication required. EPSS data not available, no KEV listing identified, but public vendor advisory and tagged releases confirm the issue and provide specific fix versions.
Null pointer dereference in Firebird SQL server causes remote denial-of-service when unauthenticated attackers send malformed op_crypt_key_callback packets. Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14 are affected. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms trivial remote exploitation requiring no authentication or user interaction, allowing attackers who know only the server's IP and port to crash database services. The integrity impact rating (I:L) suggests potential for limited data corruption alongside the high availability impact. Vendor-released patches are available in versions 5.0.4, 4.0.7, and 3.0.14. No public exploit code or CISA KEV listing identified at time of analysis, though the low attack complexity makes weaponization straightforward.
Remote denial-of-service in Firebird database server versions prior to 5.0.4, 4.0.7, and 3.0.14 allows unauthenticated network attackers to crash the server via malformed authentication packets. Exploitable by sending out-of-order CNCT_specific_data segments during connection setup, triggering a negative size calculation and segmentation fault. No authentication, credentials, or special configuration required - only knowledge of server IP and port. CVSS 8.2 (High) with network vector, low complexity, and no privileges required. No public exploit code or active exploitation (CISA KEV) identified at time of analysis, though the attack surface is maximally exposed given the unauthenticated network vector and low complexity (AV:N/AC:L/PR:N).
Remote unauthenticated denial of service in Firebird SQL database server versions prior to 6.0.0/5.0.4/4.0.7/3.0.14 allows attackers to crash the database by sending a malformed op_slice network packet that triggers a null pointer dereference in the SDL_info() function. Attack requires only network access to the database port with no authentication (CVSS AV:N/AC:L/PR:N). No public exploit code identified at time of analysis, and EPSS data not available for this recent CVE. Fixed versions released by vendor across all maintained branches.
Token leakage in HashiCorp Vault and Vault Enterprise (0.11.2 up to 2.0.0, 1.21.5, 1.20.10, and 1.19.16) occurs when an auth mount is configured to pass through the 'Authorization' header and that same header is used to authenticate to Vault; in this case Vault forwards the caller's Vault token onward to the auth plugin backend. An authenticated client's token is thereby exposed to a plugin backend that should never see it, enabling potential impersonation and unauthorized secret access. No public exploit identified at time of analysis, and EPSS exploitation probability is negligible (0.01%, 3rd percentile).
Arbitrary server-side file deletion in SiYuan (b3log/SiYuan) versions 3.6.3 and prior lets a low-privileged actor with access to the /api/av/removeUnusedAttributeView endpoint - such as a Reader-role or publish context - supply an id parameter containing ../ sequences to escape the storage/av directory and delete any .json file on the server, including conf/conf.json and workspace metadata. The GitHub Security Advisory (GHSA-vw86-c94w-v3x4) includes step-by-step reproduction, so publicly available exploit code exists, but there is no public exploit identified as weaponized and SSVC exploitation status is 'none'; EPSS is low at 0.06%. Fixed in version 3.6.4.
Unauthenticated denial of service in zrok's OAuth-protected proxy shares (openziti/zrok <= 1.1.11 and v2 < 2.0.1) lets a remote attacker crash the proxy process with a single crafted Cookie header. The GetSessionCookie routine reads an attacker-controlled cookie-stripe count and performs make([]string, count) with no upper bound before any authentication, driving gigabyte-scale heap allocations that cause OOM termination or goroutine panics across every share the proxy serves. There is no public exploit identified at time of analysis, and EPSS is low (0.06%), but exploitation is trivially automatable per CISA SSVC.
Command injection in radare2's rabin2 PDB parser allows local attackers to execute arbitrary commands when the tool is compiled without SSL support on UNIX systems. The vulnerability (CWE-78) affected a narrow window between commits 01ca2f6 and 9236f44 (post-6.1.2, pre-6.1.3), spanning less than one week in the development timeline. CVSS 7.4 (HIGH) reflects local attack vector with high complexity but no authentication required. No active exploitation confirmed (not in CISA KEV), though publicly available exploit code exists. EPSS data not provided. Fixed in commit 9236f44a28 per GitHub PR #25651.
Logic error in Luanti 5 (formerly Minetest) game engine before 5.15.2 allows malicious mods to gain unauthorized access to security-restricted APIs by intercepting mod environment setup. When any mod is designated as trusted (via secure.trusted_mods or secure.http_mods), a specially crafted mod can exploit the environment initialization sequence to receive the insecure environment or HTTP API access intended only for trusted mods. CVSS 8.1 reflects local attack vector with high complexity but no authentication required and scope change with high confidentiality/integrity/availability impact. GitHub security advisory and two fix commits confirm patch availability. No CISA KEV listing or public exploit code identified at time of analysis.
Dgraph distributed GraphQL database versions ≤25.3.1 expose admin authentication tokens through an unauthenticated /debug/pprof/cmdline endpoint, allowing remote attackers to retrieve the token from process command line arguments and gain full administrative access to the database. The vulnerability combines unauthenticated information disclosure (CWE-200) with subsequent authentication bypass, enabling configuration changes and operational control. Fixed in version 25.3.2 per vendor advisory GHSA-95mq-xwj4-r47p. CVSS 9.4 (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation against default configurations with no authentication required.
Authentication bypass in OAuth2 Proxy allows unauthenticated remote attackers to access protected resources by spoofing the X-Forwarded-Uri header when the service is configured with --reverse-proxy and at least one skip-auth route or regex. This issue, addressed in version 7.15.2, remains exploitable if the new --trusted-proxy-ip flag is not set, requiring operators to strip or overwrite the dangerous header at the reverse proxy layer. No active exploitation or public proof-of-concept code has been identified, and EPSS estimates a low 0.08% probability of exploitation.
Denial of service vulnerability in Go Markdown's SmartypantsRenderer leads to a panic or out-of-bounds read when processing malformed input containing an unmatched '<' character. Unauthenticated remote attackers can crash services using the library by supplying crafted Markdown content, causing service disruption. A public proof-of-concept exists, but exploitation probability is low (EPSS 0.04%) and no active exploitation has
Path traversal in Zarf package inspection commands enables arbitrary file write when processing malicious packages. Attackers can craft Zarf packages with traversal sequences in the Metadata.Name field (e.g., '../../etc/cron.d/malicious'), bypassing input validation to write attacker-controlled content to sensitive system locations when users run 'zarf package inspect sbom' or 'zarf package inspect documentation'. Fixed in version v0.74.2. CVSS 7.1 (High) with network attack vector but requires user interaction. No public exploit identified at time of analysis, though exploitation complexity is low as attackers only need to modify zarf.yaml and sboms.tar in a package archive.
Unauthenticated SFTP file access in goshs occurs when the documented empty-username basic-auth syntax `-b ':pass'` is used with `-sftp`. This logic flaw leaves password authentication unenforced, allowing remote attackers to read, upload, rename, and delete files within the configured SFTP root. A publicly available proof-of-concept exists but no active exploitation has been reported.
Authenticated SFTP users in goshs (a Go-based HTTP/SFTP file server) can read and write files outside the configured SFTP root directory via a path validation bypass. The vulnerability affects the SFTP subsystem in goshs beta.4 and earlier v2.x versions, exploiting a flawed string-prefix check that treats sibling directories (e.g., /tmp/goshsroot_evil) as valid when the configured root is /tmp/goshsroot. Public exploit code exists with video demonstrations showing complete jail escape, allowing authenticated attackers to list directories, download sensitive files, create arbitrary directories, and upload malicious content outside the intended boundary. Fix released in goshs v2.0.0 per vendor advisory GHSA-5h6h-7rc9-3824.
Authentication bypass in OAuth2 Proxy versions before 7.15.2 allows remote unauthenticated attackers to access protected resources when deployed with nginx auth_request integration and health check features enabled. Attackers can spoof health check User-Agent headers to bypass OAuth2 authentication entirely, gaining unauthorized access to upstream applications. CVSS 9.1 (Critical) reflects network-accessible, low-complexity attack requiring no privileges or user interaction. No active exploitation confirmed (not in CISA KEV), but the trivial attack complexity and authentication bypass impact warrant immediate patching in affected deployments using nginx auth_request with --ping-user-agent or --gcp-healthchecks flags.
Kyverno's apiCall service helper automatically injects the controller's ServiceAccount token into HTTP requests when ClusterPolicy or GlobalContextEntry authors omit an Authorization header, enabling token exfiltration to attacker-controlled endpoints via confused deputy vulnerability. Affects deployments where policy YAML repositories are compromised (GitOps threat model) or ClusterPolicy creation is possible. CVSS 8.1 (High) reflects network attack vector with low complexity and low privileges required. No CISA KEV listing or public exploit identified at time of analysis, but GitHub advisory includes working proof-of-concept demonstrating token injection and exfiltration.
Linux kernel rxrpc subsystem allows remote denial of service via malformed RESP challenge packets due to incorrect serial number comparison logic. The rxrpc_post_response() function compares challenge serial numbers from the wrong packet structure, causing response queue corruption that can crash the kernel networking stack. This affects Linux kernel versions containing commit 5800b1cf3fd8 through the 6.16-6.19 and 7.0 series. Patches are available from kernel.org for affected stable branches. EPSS exploitation probability is very low (0.02%, 4th percentile) and no public exploits or active exploitation have been identified, suggesting limited real-world risk despite the network-accessible attack vector.
Out-of-bounds read in Linux kernel's rxrpc rxgk authentication handler allows remote unauthenticated attackers to trigger information disclosure and denial of service via malformed RESPONSE authenticator packets. The vulnerability stems from incorrect pointer arithmetic in rxgk_verify_authenticator() that inflates the parser boundary check by a factor of four, allowing reads beyond kmalloc() buffer boundaries. Vendor patches available for kernel versions 6.18.23, 6.19.13, and 7.0. EPSS score of 0.02% (4th percentile) suggests low observed exploitation probability despite network attack vector, though KASAN reports confirm reproducibility.
A double-free vulnerability in the Linux kernel's SMB Direct (RDMA transport) server implementation allows remote unauthenticated attackers to trigger memory corruption with high CVSS 9.8 severity. The flaw occurs when smb_direct_free_sendmsg() is called twice on the same memory region after smb_direct_flush_send_list() moves messages to a batch list. Vendor patches available across kernel versions 6.18.24, 6.19.14, and 7.0.1, with upstream commits confirmed in stable branches. Despite critical CVSS scoring, EPSS probability remains very low at 0.02% (4th percentile) and no active exploitation or public POC identified, suggesting limited real-world targeting of this SMB Direct RDMA feature.
Use-after-free in Linux kernel MediaTek video encoder allows local authenticated users to corrupt memory and potentially execute arbitrary code. The flaw affects the vcodec driver's encoder release path where ctx memory is freed before canceling scheduled workqueue tasks, enabling race conditions between cleanup and worker threads that may dereference freed memory. KASAN-confirmed exploitation requires local access with low privileges (CVSS AV:L/PR:L). Patches available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS score of 0.02% (5th percentile) indicates very low probability of automated exploitation, with no public exploit identified at time of analysis.
Out-of-bounds memory access in Linux Kernel's KVM subsystem for LoongArch architecture allows local authenticated attackers with low privileges to read limited kernel memory and cause system crashes. The vulnerability stems from improper handling of empty EIOINTC coremap values in eiointc_update_sw_coremap(), resulting in invalid array indexing into kvm_arch::phyid_map::phys_map[]. While CVSS rates this 7.3 HIGH, the EPSS score of 0.02% (4th percentile) indicates minimal real-world exploitation activity. No active exploitation (not in CISA KEV) or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.18.21, 6.19.11, 7.0, and mainline).
Out-of-bounds array access in Linux kernel KVM subsystem on LoongArch allows local authenticated attackers with low privileges to execute arbitrary code, escalate privileges, or cause denial of service by passing negative cpuid values to kvm_get_vcpu_by_cpuid(). The function lacks bounds checking before indexing phyid_map::phys_map[], enabling read/write beyond array boundaries with container escape potential (CVSS scope change). Vendor patches available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11). EPSS score of 0.02% indicates low automated exploitation likelihood, with no confirmed active exploitation or public POC at time of analysis.
Address calculation error in Linux kernel KVM on ARM64 allows local authenticated attackers with low privileges to corrupt memory descriptors, potentially enabling container escape or privilege escalation to compromise host integrity and confidentiality. The vulnerability affects KVM's stage-1/stage-2 page table descriptor swapping logic where pointer arithmetic incorrectly multiplies the offset by 8, causing writes to unintended memory locations. Vendor patches available for Linux 6.19.11 and mainline with EPSS exploitation probability at 5th percentile, indicating low observed exploitation despite high CVSS severity.
Denial of service via CPU soft lockup in Linux kernel's wlcore Wi-Fi driver (versions 5.10 through 7.0) occurs when memory allocation fails during wireless frame transmission. Incorrect error code return (-EAGAIN instead of -ENOMEM) triggers infinite retry loop while holding critical mutex, causing system unresponsiveness. Vendor-released patches available across all affected stable kernel branches (5.10.253, 5.15.203, 6.1.167, 6.6.130, 6.12.78, 6.18.20, 6.19.10, 7.0). CVSS 7.5 (High) reflects network attack vector with no authentication required, though EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. No active exploitation confirmed (not in CISA KEV); no public exploit identified at time of analysis.
Use-after-free in Linux kernel tracing subsystem allows local authenticated attackers to achieve arbitrary code execution, privilege escalation, or denial of service. The vulnerability occurs when deleting tracing instances with copy_trace_marker enabled, where improper RCU synchronization leaves freed memory accessible. Exploitation requires local access with low privileges to manipulate kernel tracing facilities. EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability. Vendor patches available across multiple stable kernel versions (6.18.20, 6.19.10, 7.0).
Denial of service in Linux kernel SMB server (ksmbd) affects versions 6.18 through 7.0-rc via race condition in SMBDirect receive credit management. Remote unauthenticated attackers can trigger resource exhaustion through crafted SMB packets exploiting the window between hardware reception and completion processing. Vendor patches released for stable branches 6.18.11, 6.19.1, and mainline 7.0. Low EPSS score (0.02%) indicates limited exploitation interest despite network attack vector and no authentication requirement.
Use-after-free in Linux kernel SMB server (ksmbd) RDMA handling allows remote unauthenticated attackers to execute arbitrary code, escalate privileges, or crash the system via crafted SMB Direct connections. The vulnerability arises when batched RDMA send operations without IB_SEND_SIGNALED flags are prematurely freed during connection failures, causing memory corruption. Vendor patches are available for kernel versions 6.18.11, 6.19.1, and 7.0. EPSS score of 0.02% suggests low observed exploitation probability, and no active exploitation or public POC is confirmed at time of analysis, though the critical CVSS score (9.8) reflects severe potential impact if the SMB Direct feature is enabled.
A type assertion bug in Kyverno's forEach mutation handler crashes the cluster-wide background controller into CrashLoopBackOff and blocks admission controller operations, causing denial of service for policy-matched resources. Any authenticated user with Policy or ClusterPolicy creation permissions can trigger the crash by creating a malformed policy. The vulnerability affects Kyverno versions prior to 1.17.2 and 1.16.4, is limited to the legacy policy engine (CEL-based policies unaffected), and persists until the malicious policy is deleted. Vendor-released patches available with confirmed fix commits on GitHub.
Kyverno's apiCall feature automatically attaches the admission controller's ServiceAccount token to HTTP requests without validating the destination URL, enabling authenticated attackers to exfiltrate tokens to attacker-controlled servers and achieve full cluster compromise through webhook configuration tampering. Affects Kyverno versions prior to 1.18.0-rc1, 1.17.2-rc1, and 1.16.4. Vendor-released patches available across all three affected version branches. EPSS data not provided, but the vulnerability enables privilege escalation from low-privilege Kubernetes user to cluster admin via token theft, representing critical risk in multi-tenant environments.
Cross-namespace privilege escalation in Kyverno 1.17.x allows authenticated namespace administrators to bypass RBAC controls and read ConfigMaps from any Kubernetes namespace. The vulnerability exploits unvalidated `configMap.namespace` field in Kyverno's ConfigMap context loader, enabling attackers to leverage Kyverno's privileged service account permissions. This is a regression following incomplete fix for CVE-2026-22039, which addressed the same issue in `apiCall` context but missed the ConfigMap loader. Patch available in version 1.17.2. CVSS 7.7 with Changed Scope indicates significant multi-tenant cluster risk; EPSS data not available but the regression nature and RBAC bypass impact warrant immediate patching in multi-tenant environments.
Lua code injection in Contour (Kubernetes ingress controller for Envoy) from v1.19.0 through the fixes in v1.31.6/v1.32.5/v1.33.4 lets a low-privileged tenant achieve arbitrary code execution inside the shared Envoy proxy. A user with RBAC rights to create or modify HTTPProxy resources injects Lua via the cookie-rewrite pathRewrite.value field; although the code only runs on the attacker's own route, it executes in shared infrastructure and can steal Envoy's xDS credentials (exposing other tenants' TLS keys) or cause denial of service for co-tenants. No public exploit identified at time of analysis, and EPSS is low (0.07%, 22nd percentile), consistent with the requirement for pre-existing cluster RBAC access.
Denial of service in the Argo Workflows controller (versions 3.6.5 through 4.0.4, plus the 3.7.0-rc1 through 3.7.12 pre-releases) lets any user able to submit a workflow crash-loop the entire controller by attaching a malformed workflows.argoproj.io/pod-gc-strategy pod annotation that contains no '/' separator, triggering an out-of-range index panic in an informer goroutine that sits outside the controller's recover() scope. Because the poisoned pod persists across restarts, the controller enters CrashLoopBackOff and halts all workflow processing cluster-wide until the pod is manually deleted. A working proof-of-concept manifest is published in the GHSA advisory (SSVC exploitation status: poc), but there is no evidence of active exploitation and EPSS is very low at 0.04%.
Command injection in radare2 PDB parser (versions before 6.1.4) enables arbitrary OS command execution when users analyze malicious PDB files. Publicly available exploit code exists. Attackers craft PDB files with newline characters in symbol names to inject radare2 commands during flag renaming operations, which then execute OS commands via radare2's shell operator when victims run the 'idp' command. CVSS 8.4 reflects local attack vector requiring user interaction, though EPSS data not available. Patch released in version 6.1.4 with detailed technical disclosure at blog.calif.io showing 0-day discovery process.
Memory corruption in rust-openssl's key derivation functions allows heap or stack buffer overflow when applications pass undersized buffers to Deriver::derive or PkeyCtxRef::derive on OpenSSL 1.1.x. The vulnerability affects X25519, X448, DH, and HKDF-extract operations where OpenSSL ignores the caller-specified buffer length and unconditionally writes the full shared secret, causing safe Rust code to trigger memory corruption. Vendor patch available in v0.10.78; OpenSSL 3.x deployments are not affected as newer providers correctly validate buffer lengths.
Out-of-bounds memory write in rust-openssl's AES key unwrap function allows attackers who control buffer sizes to corrupt memory via safe API misuse. The aes::unwrap_key() function contains an inverted bounds assertion that accepts undersized output buffers and rejects correctly sized ones, causing the function to write beyond allocated memory by in_.len() - 8 - out.len() bytes. Vendor patch available via GitHub PR #2604 and commit 718d07ff, released in openssl-v0.10.78. No evidence of active exploitation (not in CISA KEV) or public proof-of-concept at time of analysis, but the logic flaw is clearly documented in vendor advisory GHSA-8c75-8mhr-p7r9.
Stack-based buffer overflow in rust-openssl's MdCtxRef::digest_final() allows safe Rust code to corrupt memory when EVP_DigestFinal() writes beyond the provided output buffer boundary. The vulnerability occurs when the output buffer is smaller than EVP_MD_CTX_size(ctx), causing EVP_DigestFinal() to write past the buffer end and corrupt stack memory. Vendor-released patch available in version 0.10.78 via GitHub commit 826c3888. No public exploit identified at time of analysis, but exploitable from memory-safe Rust code paths, violating Rust's safety guarantees.
Server-side request forgery in monetr's Lunch Flow integration allows authenticated users on self-hosted instances to force the server to issue HTTP GET requests to arbitrary URLs, with response bodies from failed requests reflected in API error messages. This enables information disclosure attacks against internal networks, cloud metadata endpoints (AWS EC2 instance metadata without IMDSv2), and RFC1918 private addresses. The vulnerability is compounded by unbounded response buffering that creates a denial-of-service vector via memory exhaustion. Patch available in v1.12.5. The hosted my.monetr.app service is not affected as Lunch Flow is disabled there. Self-hosted instances with default configuration (Lunch Flow enabled, public signup allowed) are at highest risk.
SQL injection in Daptin's `/aggregate/:typename` endpoint allows authenticated low-privilege users to extract arbitrary database content via unsanitized query parameters. The `column` and `group` parameters are passed directly to raw SQL literal expressions without validation, enabling data exfiltration from any table including user credentials, database schema disclosure, and cross-table correlation attacks. Patched in version 0.11.4 which replaces all raw SQL construction with parameterized queries and schema-based validation. No evidence of active exploitation or public POC at time of analysis, though exploitation is straightforward for authenticated users.
Complete authentication bypass in openvpn-auth-oauth2 plugin mode (v1.26.3-1.27.2) grants VPN access to unauthenticated clients. Legacy OpenVPN clients lacking WebAuth/SSO support bypass OIDC authentication entirely and gain full network access due to incorrect plugin return codes. Only the experimental shared-library plugin deployment is affected; the default management-interface mode is not vulnerable. Vendor patch released in v1.27.3 with confirmed fix commits. No active exploitation reported, but trivial to exploit with standard Linux openvpn CLI against vulnerable deployments.
Remote attackers can corrupt PowerDNS Authoritative Server configuration via specially crafted DNS NOTIFY requests, causing persistent denial of service requiring manual administrator intervention. The attack adds malformed secondary domains to the bind backend, rendering the configuration invalid and preventing the server from restarting. No active exploitation confirmed at time of analysis, but the network-accessible attack vector and lack of authentication requirements elevate risk for internet-facing authoritative DNS servers.
Remote denial of service in dnsdist allows unauthenticated attackers to crash the DNS load balancer by sending specially crafted DNSCrypt queries that trigger a divide-by-zero error. The vulnerability requires no authentication, low attack complexity, and directly impacts service availability for all DNS traffic routed through affected dnsdist instances. Organizations using DNSCrypt protocol support in dnsdist face immediate risk of service disruption from remote attackers.
Use-after-free in Linux kernel CXL (Compute Express Link) subsystem allows local authenticated attackers to corrupt memory and potentially execute arbitrary code or cause kernel panics. The flaw occurs in cxl_detach_ep() during device removal when parent port references are freed prematurely, before child operations complete. Affects Linux kernel 6.3 through 7.0-rc5; patched in versions 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% indicates low exploitation probability. No active exploitation or public exploit code identified at time of analysis.
Double-free memory corruption in Linux kernel bcmasp network driver allows local authenticated attackers with low privileges to achieve arbitrary code execution, privilege escalation, or system crash. The vulnerability affects kernel versions 6.6 through early 7.0 release candidates. Vendor patches available across stable branches (6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (5th percentile) indicates very low real-world exploitation probability, and no active exploitation or public POC has been identified. This represents a low-priority issue for most environments despite the 7.8 CVSS score, as it requires local authenticated access and affects only systems using the specific bcmasp Broadcom network driver.
Use-after-free in Linux kernel RDMA/EFA driver allows local authenticated users with low privileges to execute arbitrary code with high confidentiality, integrity, and availability impact. The vulnerability affects the admin queue completion handling where completion context data is accessed after being freed, creating a window for memory corruption exploitation. Affects kernel versions from 5.12 through 7.0-rc7, with vendor patches available for stable branches 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability, and no public exploit code or CISA KEV listing identified at time of analysis.
Use-after-free in Linux kernel's xe GPU driver allows local authenticated users to execute arbitrary code with kernel privileges. The vulnerability occurs in the SR-IOV physical function migration restore path when error handling fails to nullify a freed data pointer, enabling subsequent write operations to reference deallocated memory. With CVSS 7.8 (High) and very low EPSS (0.02%), this represents typical kernel memory corruption risk requiring local access and low privileges. Vendor patches are available for affected 6.19 and 7.0-rc versions.
Memory exhaustion and kernel crash in Linux kernel's ksmbd SMB server allows remote unauthenticated denial of service via crafted lock requests. The smb2_lock() function contains three critical error-handling defects: memory leaks when vfs_lock_file() returns unexpected errors, stale error propagation in UNLOCK operations, and NULL pointer dereference during rollback when smb_flock_init() allocation fails. CVSS vector indicates network-accessible, low-complexity exploitation requiring no authentication. EPSS score of 0.02% (7th percentile) suggests minimal observed scanning activity, and no KEV listing confirms no widespread exploitation detected. However, the network attack vector (AV:N) and high availability impact (A:H) make this a realistic DoS risk for systems running ksmbd. Vendor patches available across stable kernel series 5.15-6.19.
Memory corruption in the Linux kernel sma1307 ASoC driver allows local authenticated users to trigger a double-free condition leading to potential privilege escalation, denial of service, or information disclosure. The vulnerability stems from improper cleanup of device-managed memory allocations in error paths within the sma1307_setting_loaded() function, where devm_kzalloc()-allocated resources are incorrectly freed with kfree(), causing devres to later release the same memory a second time. Vendor patches are available across multiple stable kernel branches (6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability, and no active exploitation or public POC has been identified.
Out-of-bounds write in Linux kernel ksmbd allows authenticated remote attackers to cause memory corruption via crafted SMB2 compound requests combining QUERY_DIRECTORY and QUERY_INFO commands. The vulnerability arises when get_file_all_info() fails to validate OutputBufferLength against available buffer space before converting filenames to UTF-16, enabling buffer overflow beyond response buffer boundaries. With CVSS 8.8 (High) and network attack vector requiring only low privileges, this presents significant risk to systems running ksmbd SMB server. Vendor patches available across multiple kernel versions (5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS exploitation probability remains low at 0.01% (2nd percentile), and no public exploit or CISA KEV listing identified at time of analysis.
Authentication bypass in MinIO object storage allows remote attackers to write arbitrary objects to any bucket using only a valid access key, without the corresponding secret key or cryptographic signature. The vulnerability affects MinIO RELEASE.2023-05-18T00-05-36Z through RELEASE.2026-04-11T03-20-12Z. Attackers can impersonate any user with WRITE permissions by exploiting a logic flaw in the STREAMING-UNSIGNED-PAYLOAD-TRAILER code path that incorrectly validates credentials from query parameters while bypassing signature verification. Vendor-released patch available in RELEASE.2026-04-11T03-20-12Z (GitHub commit 76913a9f). No public exploit identified at time of analysis, but exploitation requires only knowledge of a valid access key and target bucket name.
Authentication bypass in MinIO RELEASE.2023-05-18T00-05-36Z through RELEASE.2026-04-11T03-20-12Z allows remote unauthenticated attackers to write arbitrary objects to any bucket by exploiting an unvalidated auth type in the Snowball auto-extract handler. Attackers need only a valid access key (including the default 'minioadmin') and can fabricate signatures without knowing the secret key. CVSS 8.8 reflects network-accessible, low-complexity exploitation with no authentication required (CVSS:4.0 PR:N). No public exploit identified at time of analysis, but exploitation requires only basic S3 API knowledge. Patched in RELEASE.2026-04-11T03-20-12Z per vendor advisory GHSA-9c4q-hq6p-c237.
Unauthenticated remote attackers can crash free5GC Policy Control Function (PCF) versions before 1.4.3 via repeated HTTP requests to the OAM endpoint over the Service-Based Interface. Each request leaks memory by registering duplicate CORS middleware in the Gin router handler chain, causing progressive memory exhaustion that prevents all User Equipment from establishing 5G sessions. Patched in version 1.4.3 via commit 599803b. EPSS data unavailable; not listed in CISA KEV. CVSS 7.5 High severity reflects network-accessible unauthenticated attack with high availability impact.
Authentication bypass in OAuth2 Proxy 7.5.0-7.15.1 allows remote unauthenticated attackers to access protected resources by exploiting path normalization discrepancies between the proxy and backend services. When deployments use skip_auth_routes or skip_auth_regex with broad wildcard patterns, attackers can inject '#' or '%23' (URL-encoded fragment delimiter) to match public allowlist rules while the upstream application serves sensitive endpoints. CVSS 8.2 (AV:N/AC:L/PR:N/UI:N) reflects network-based unauthenticated access; no public exploit identified at time of analysis. EPSS data not provided. Fixed in version 7.15.2 through conservative path normalization.
Authentication bypass in Oxia (oxia-db) metadata store and coordination system prior to 0.16.2 allows an attacker holding a valid OIDC/JWT token issued for a different service by the same identity provider to authenticate to Oxia. The OIDC provider unconditionally set SkipClientIDCheck: true in the go-oidc verifier, disabling library-level audience (aud) validation and breaking the audience/tenant isolation that OAuth2/OIDC relies on. There is no public exploit identified at time of analysis, EPSS is very low (0.05%), and CISA SSVC records no known exploitation, but the technical impact is rated total.
Sensitive information disclosure in Oxia (a metadata store and coordination system) prior to 0.16.2 causes the full OIDC bearer token to be written in plaintext to application logs at DEBUG level whenever authentication fails. Anyone able to read those logs - via a compromised or shared log aggregation pipeline or misconfigured log access controls - can harvest valid JWTs (header, payload, and signature) and replay them to impersonate legitimate users. No public exploit identified at time of analysis; EPSS is low at 0.05%, and CISA SSVC records exploitation status as none.
Denial-of-service in Oxia (metadata store and coordination system) versions <= 0.16.1 allows a remote unauthenticated client to crash the entire data server process by racing rapid KeepAlive/heartbeat requests against session expiry or closure. The flaw is a concurrency bug (send on closed channel panic, or deadlock when the buffer fills) triggerable without authentication over the network. No public exploit identified at time of analysis; EPSS is low (0.04%) and CISA SSVC rates exploitation as none, but the low attack complexity makes it a credible availability threat once patched.
Remote denial of service in Coturn TURN/STUN server allows unauthenticated attackers to crash ARM64 deployments with a single malformed UDP packet. The vulnerability triggers a fatal SIGBUS signal via misaligned memory access during STUN attribute parsing, requiring no authentication or special configuration. All ARM64 installations of Coturn prior to 4.10.0 are vulnerable to instant process termination. EPSS exploitation probability is not yet available as this is a newly disclosed CVE, but the attack complexity is low (AC:L) and requires no privileges (PR:N), making exploitation trivial once awareness spreads in attacker communities.
Local privilege escalation in CivetWeb v1.16 service allows authenticated users to execute arbitrary code with SYSTEM privileges via unquoted service path exploitation. The Windows service configuration lacks quotes around 'C:\Program Files\CivetWeb\CivetWeb.exe', enabling attackers to place malicious executables in directories scanned before the intended path (e.g., 'C:\Program.exe' or 'C:\Program Files\CivetWeb.exe'). No public exploit identified at time of analysis, though EPSS data not available. Patch available per vendor advisory from INCIBE.
Unauthenticated remote attackers can obtain sensitive information from Firefox's IP Protection component prior to version 150 via network-accessible requests with low attack complexity.

Despite a CVSS base score of 7.5 (High), real-world exploitation risk appears limited: EPSS probability is only 0.02% (5th percentile), no public exploit code has been identified, and CISA SSVC framework rates it as non-exploited with partial technical impact, though automatable.
Integer overflow in OpenEXR's DWA compressor (versions 3.2.0-3.2.7, 3.3.0-3.3.9, 3.4.0-3.4.9) enables local attackers to trigger memory corruption when processing maliciously crafted EXR image files requiring user interaction. This vulnerability represents a missed instance of the same integer overflow pattern addressed in related CVEs 2026-34589, 34588, and 34544, occurring in `internal_dwa_compressor.h:1040` where width multiplication lacks proper size_t casting. Given the local attack vector requiring user interaction (CVSS AV:L/UI:A), real-world exploitation requires social engineering to trick users into opening weaponized EXR files, making this primarily a workstation-targeted threat in media production environments. No active exploitation or public POC identified at time of analysis.
Privilege escalation in Neko virtual browser (versions 3.0.0-3.0.10, 3.1.0-3.1.1) allows any authenticated user with low privileges to immediately gain full administrative control over the entire instance, including member management, room settings, broadcast control, and session termination. This complete instance compromise requires only network access and valid user credentials (CVSS 8.8, AV:N/AC:L/PR:L). While EPSS exploitation probability is low (0.12%, 31st percentile) and no active exploitation has been confirmed, the vulnerability is trivially exploitable by any authenticated user and classified as non-automatable but with total technical impact per SSVC. Vendor patches are available in versions 3.0.11 and 3.1.2.
Server-Side Request Forgery in Glances IP plugin allows authenticated attackers to force the monitoring application to send HTTP requests to arbitrary internal or external endpoints, with automatic credential leakage when public_username and public_password are configured. The vulnerability affects all versions prior to 4.5.4 and arises from insufficient validation of the public_api configuration parameter. EPSS exploitation probability is low (0.04%, 12th percentile), but SSVC framework confirms proof-of-concept availability and automatable exploitation with partial technical impact. Vendor patch released in version 4.5.4.
Cross-origin data exfiltration in Glances web server allows remote unauthenticated attackers to read sensitive system information (CPU, memory, processes, network stats) through the REST API endpoint /api/4/* via malicious websites exploiting permissive CORS policy. Affects all versions prior to 4.5.4. EPSS score of 0.06% (18th percentile) suggests low widespread exploitation probability despite proof-of-concept availability, though the network-accessible, unauthenticated attack vector (AV:N/PR:N) combined with high confidentiality impact (VC:H) makes this a priority for internet-exposed instances.
Buffer overflow in glibc's obsolete NIS authentication function allows remote attackers to compromise integrity and availability via spoofed UDP responses. Affects all glibc versions through 2.43, but exploitation requires the target application to actively use the deprecated nis_local_principal function (obsolete since glibc 2.26). EPSS score of 0.02% (5th percentile) indicates low real-world exploitation probability, consistent with the narrow attack surface of legacy NIS deployments. No active exploitation or public exploit code identified at time of analysis.
Disabled user accounts in Nginx UI versions before 2.3.4 retain full API access through previously issued JWT tokens for the entire token lifetime, allowing attackers with stolen credentials to maintain persistent access and create new accounts even after administrative remediation attempts. This authentication bypass enables continued confidentiality and integrity compromise of Nginx configurations despite account lockout. Reported by GitHub security advisories; no evidence of active exploitation (not in CISA KEV), but the token-reuse mechanism makes exploitation straightforward for attackers who have already obtained credentials.
Out-of-bounds read in the Linux kernel's X.509 certificate parser allows local unprivileged users to trigger memory corruption or denial of service by submitting a specially crafted certificate via the keyrings(7) API. The flaw exists in the handling of empty Basic Constraints or Key Usage extensions, where the first byte is dereferenced before the length check. A proof-of-concept was responsibly disclosed by the reporter, though no public exploit is identified at time of analysis and EPSS rates the exploitation probability as very low (0.01%).
Uncontrolled memory consumption in monetr 1.12.3 and earlier allows remote unauthenticated attackers to trigger denial of service by sending oversized payloads to the public Stripe webhook endpoint. The vulnerability affects deployments with Stripe webhooks enabled and lacks upstream body-size enforcement. Version 1.12.4 provides a fix. EPSS and KEV data not available; no public exploit confirmed at time of analysis, though the attack method is straightforward (8.2 CVSS reflecting high availability impact with low complexity).
Heap-based buffer overflow in xrdp 0.10.5 and earlier allows remote code execution after authentication via malicious EGFX graphics channel PDUs. Authenticated attackers can exploit insufficient validation of client-controlled size parameters to write beyond allocated heap buffers. Unauthenticated attackers can only trigger denial-of-service crashes. Vendor-released patch available in version 0.10.6. No active exploitation confirmed (not in CISA KEV), but heap overflows in remote services are high-value targets. Default non-privileged execution since 0.10.2 limits post-compromise impact.
Out-of-bounds read in xrdp 0.10.5 and earlier allows unauthenticated remote attackers to crash the RDP service or disclose memory contents during pre-authentication message parsing. The vulnerability (CWE-125) exploits insufficient buffer length validation in dynamic channel communication handling, affecting default installations exposed to network access. Fixed in version 0.10.6 per vendor advisory GHSA-92mr-6wpp-27jj. CVSS 8.7 reflects high availability impact; no active exploitation confirmed in CISA KEV at time of analysis, though public disclosure increases risk for internet-facing xrdp deployments.
Out-of-bounds read in xrdp RDP server versions ≤0.10.5 allows remote unauthenticated attackers to crash the service or disclose process memory by sending a malformed Confirm Active PDU during RDP capability negotiation. Attack complexity is low but requires user interaction. EPSS data not available; no CISA KEV listing or public POC identified at time of analysis. Vendor-released patch available in version 0.10.6 per GitHub security advisory GHSA-rvh9-9wm3-28c7.
Heap-based buffer overflow in xrdp's NeutrinoRDP module (versions ≤0.10.5) enables malicious downstream RDP servers or MitM attackers to achieve remote code execution or denial of service when proxying RDP sessions. Exploitation requires the victim xrdp server to have the non-default NeutrinoRDP module compiled and enabled (--enable-neutrinordp), and a user must initiate an RDP session through the affected proxy to a malicious server. EPSS data unavailable; no CISA KEV listing indicates targeted rather than widespread exploitation. Fixed in version 0.10.6.
Missing MAC signature verification in xrdp 0.10.5 and earlier allows man-in-the-middle attackers to modify encrypted RDP traffic without detection when Classic RDP Security layer is used. Unauthenticated network attackers with MITM position can alter packet contents in transit, achieving high integrity and confidentiality impact on both vulnerable and subsequent systems (CVSS 9.3, CVSS:4.0 with scope change). TLS security layer deployments are not affected. Vendor patch released in version 0.10.6. No active exploitation or public POC identified at time of analysis, but EPSS data unavailable for risk assessment.
Privilege escalation to root in xrdp 0.10.5 and earlier allows authenticated local attackers to execute arbitrary code due to improper error handling during privilege drop in the session execution component. The flaw requires low attack complexity and no user interaction (CVSS 8.8, AV:L/AC:L/PR:L/UI:N). Vendor-released patch available in xrdp v0.10.6. No public exploit or active exploitation confirmed at time of analysis, though CVSS scope change (S:C) indicates potential container/VM escape scenarios.
Remote code execution in Firebird RDBMS versions prior to 5.0.4, 4.0.7, and 3.0.14 allows authenticated users with CREATE FUNCTION privileges to execute arbitrary code as the database server process through path traversal in the external engine plugin loader. The vulnerability stems from insufficient input validation (CWE-22) when concatenating user-supplied engine names into filesystem paths, enabling attackers to load malicious shared libraries from arbitrary locations. With CVSS 10.0 and scope change (S:C), successful exploitation grants full system compromise beyond database boundaries. EPSS data not provided, no CISA KEV listing identified, indicating targeted rather than widespread exploitation at time of analysis. Vendor-released patches available across all affected major versions.
Firebird database server crashes via crafted slice packet exploiting zero-length SDL descriptor validation flaw. Remote unauthenticated attackers can trigger division-by-zero errors in the sdl_desc() function to cause denial of service against Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation with no authentication required. EPSS data not available; no public exploit identified at time of analysis, though technical details in GitHub advisory may facilitate reproduction.
Remote denial-of-service in Firebird Database Server versions prior to 5.0.4, 4.0.7, and 3.0.14 allows unauthenticated network attackers to crash the server via crafted XDR-encoded op_response packets. The xdr_status_vector() function fails to handle isc_arg_cstring status vector types during packet decoding, triggering immediate server termination. With CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) and CWE-228 (Improper Handling of Syntactically Invalid Structure), this represents a high-severity availability risk for internet-exposed Firebird instances. No active exploitation confirmed, but exploit development is trivial given the low attack complexity.
Buffer overflow in Firebird RDBMS allows remote unauthenticated attackers to crash database servers via malformed slice packets. Affects Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14 across all three maintained major release branches. The xdr_datum() deserialization function fails to validate cstring lengths against slice descriptor bounds during packet processing, enabling heap buffer overflow. CVSS 7.5 (High) with network attack vector and no authentication required. EPSS data not available, no KEV listing identified, but public vendor advisory and tagged releases confirm the issue and provide specific fix versions.
Null pointer dereference in Firebird SQL server causes remote denial-of-service when unauthenticated attackers send malformed op_crypt_key_callback packets. Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14 are affected. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms trivial remote exploitation requiring no authentication or user interaction, allowing attackers who know only the server's IP and port to crash database services. The integrity impact rating (I:L) suggests potential for limited data corruption alongside the high availability impact. Vendor-released patches are available in versions 5.0.4, 4.0.7, and 3.0.14. No public exploit code or CISA KEV listing identified at time of analysis, though the low attack complexity makes weaponization straightforward.
Remote denial-of-service in Firebird database server versions prior to 5.0.4, 4.0.7, and 3.0.14 allows unauthenticated network attackers to crash the server via malformed authentication packets. Exploitable by sending out-of-order CNCT_specific_data segments during connection setup, triggering a negative size calculation and segmentation fault. No authentication, credentials, or special configuration required - only knowledge of server IP and port. CVSS 8.2 (High) with network vector, low complexity, and no privileges required. No public exploit code or active exploitation (CISA KEV) identified at time of analysis, though the attack surface is maximally exposed given the unauthenticated network vector and low complexity (AV:N/AC:L/PR:N).
Remote unauthenticated denial of service in Firebird SQL database server versions prior to 6.0.0/5.0.4/4.0.7/3.0.14 allows attackers to crash the database by sending a malformed op_slice network packet that triggers a null pointer dereference in the SDL_info() function. Attack requires only network access to the database port with no authentication (CVSS AV:N/AC:L/PR:N). No public exploit code identified at time of analysis, and EPSS data not available for this recent CVE. Fixed versions released by vendor across all maintained branches.
Token leakage in HashiCorp Vault and Vault Enterprise (0.11.2 up to 2.0.0, 1.21.5, 1.20.10, and 1.19.16) occurs when an auth mount is configured to pass through the 'Authorization' header and that same header is used to authenticate to Vault; in this case Vault forwards the caller's Vault token onward to the auth plugin backend. An authenticated client's token is thereby exposed to a plugin backend that should never see it, enabling potential impersonation and unauthorized secret access. No public exploit identified at time of analysis, and EPSS exploitation probability is negligible (0.01%, 3rd percentile).
Arbitrary server-side file deletion in SiYuan (b3log/SiYuan) versions 3.6.3 and prior lets a low-privileged actor with access to the /api/av/removeUnusedAttributeView endpoint - such as a Reader-role or publish context - supply an id parameter containing ../ sequences to escape the storage/av directory and delete any .json file on the server, including conf/conf.json and workspace metadata. The GitHub Security Advisory (GHSA-vw86-c94w-v3x4) includes step-by-step reproduction, so publicly available exploit code exists, but there is no public exploit identified as weaponized and SSVC exploitation status is 'none'; EPSS is low at 0.06%. Fixed in version 3.6.4.
Unauthenticated denial of service in zrok's OAuth-protected proxy shares (openziti/zrok <= 1.1.11 and v2 < 2.0.1) lets a remote attacker crash the proxy process with a single crafted Cookie header. The GetSessionCookie routine reads an attacker-controlled cookie-stripe count and performs make([]string, count) with no upper bound before any authentication, driving gigabyte-scale heap allocations that cause OOM termination or goroutine panics across every share the proxy serves. There is no public exploit identified at time of analysis, and EPSS is low (0.06%), but exploitation is trivially automatable per CISA SSVC.
Command injection in radare2's rabin2 PDB parser allows local attackers to execute arbitrary commands when the tool is compiled without SSL support on UNIX systems. The vulnerability (CWE-78) affected a narrow window between commits 01ca2f6 and 9236f44 (post-6.1.2, pre-6.1.3), spanning less than one week in the development timeline. CVSS 7.4 (HIGH) reflects local attack vector with high complexity but no authentication required. No active exploitation confirmed (not in CISA KEV), though publicly available exploit code exists. EPSS data not provided. Fixed in commit 9236f44a28 per GitHub PR #25651.
Logic error in Luanti 5 (formerly Minetest) game engine before 5.15.2 allows malicious mods to gain unauthorized access to security-restricted APIs by intercepting mod environment setup. When any mod is designated as trusted (via secure.trusted_mods or secure.http_mods), a specially crafted mod can exploit the environment initialization sequence to receive the insecure environment or HTTP API access intended only for trusted mods. CVSS 8.1 reflects local attack vector with high complexity but no authentication required and scope change with high confidentiality/integrity/availability impact. GitHub security advisory and two fix commits confirm patch availability. No CISA KEV listing or public exploit code identified at time of analysis.
Dgraph distributed GraphQL database versions ≤25.3.1 expose admin authentication tokens through an unauthenticated /debug/pprof/cmdline endpoint, allowing remote attackers to retrieve the token from process command line arguments and gain full administrative access to the database. The vulnerability combines unauthenticated information disclosure (CWE-200) with subsequent authentication bypass, enabling configuration changes and operational control. Fixed in version 25.3.2 per vendor advisory GHSA-95mq-xwj4-r47p. CVSS 9.4 (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation against default configurations with no authentication required.
Authentication bypass in OAuth2 Proxy allows unauthenticated remote attackers to access protected resources by spoofing the X-Forwarded-Uri header when the service is configured with --reverse-proxy and at least one skip-auth route or regex. This issue, addressed in version 7.15.2, remains exploitable if the new --trusted-proxy-ip flag is not set, requiring operators to strip or overwrite the dangerous header at the reverse proxy layer. No active exploitation or public proof-of-concept code has been identified, and EPSS estimates a low 0.08% probability of exploitation.
Denial of service vulnerability in Go Markdown's SmartypantsRenderer leads to a panic or out-of-bounds read when processing malformed input containing an unmatched '<' character. Unauthenticated remote attackers can crash services using the library by supplying crafted Markdown content, causing service disruption. A public proof-of-concept exists, but exploitation probability is low (EPSS 0.04%) and no active exploitation has
Path traversal in Zarf package inspection commands enables arbitrary file write when processing malicious packages. Attackers can craft Zarf packages with traversal sequences in the Metadata.Name field (e.g., '../../etc/cron.d/malicious'), bypassing input validation to write attacker-controlled content to sensitive system locations when users run 'zarf package inspect sbom' or 'zarf package inspect documentation'. Fixed in version v0.74.2. CVSS 7.1 (High) with network attack vector but requires user interaction. No public exploit identified at time of analysis, though exploitation complexity is low as attackers only need to modify zarf.yaml and sboms.tar in a package archive.
Unauthenticated SFTP file access in goshs occurs when the documented empty-username basic-auth syntax `-b ':pass'` is used with `-sftp`. This logic flaw leaves password authentication unenforced, allowing remote attackers to read, upload, rename, and delete files within the configured SFTP root. A publicly available proof-of-concept exists but no active exploitation has been reported.
Authenticated SFTP users in goshs (a Go-based HTTP/SFTP file server) can read and write files outside the configured SFTP root directory via a path validation bypass. The vulnerability affects the SFTP subsystem in goshs beta.4 and earlier v2.x versions, exploiting a flawed string-prefix check that treats sibling directories (e.g., /tmp/goshsroot_evil) as valid when the configured root is /tmp/goshsroot. Public exploit code exists with video demonstrations showing complete jail escape, allowing authenticated attackers to list directories, download sensitive files, create arbitrary directories, and upload malicious content outside the intended boundary. Fix released in goshs v2.0.0 per vendor advisory GHSA-5h6h-7rc9-3824.
Authentication bypass in OAuth2 Proxy versions before 7.15.2 allows remote unauthenticated attackers to access protected resources when deployed with nginx auth_request integration and health check features enabled. Attackers can spoof health check User-Agent headers to bypass OAuth2 authentication entirely, gaining unauthorized access to upstream applications. CVSS 9.1 (Critical) reflects network-accessible, low-complexity attack requiring no privileges or user interaction. No active exploitation confirmed (not in CISA KEV), but the trivial attack complexity and authentication bypass impact warrant immediate patching in affected deployments using nginx auth_request with --ping-user-agent or --gcp-healthchecks flags.
Kyverno's apiCall service helper automatically injects the controller's ServiceAccount token into HTTP requests when ClusterPolicy or GlobalContextEntry authors omit an Authorization header, enabling token exfiltration to attacker-controlled endpoints via confused deputy vulnerability. Affects deployments where policy YAML repositories are compromised (GitOps threat model) or ClusterPolicy creation is possible. CVSS 8.1 (High) reflects network attack vector with low complexity and low privileges required. No CISA KEV listing or public exploit identified at time of analysis, but GitHub advisory includes working proof-of-concept demonstrating token injection and exfiltration.
