Red Hat Jboss Enterprise Application Platform 8
Monthly
The AdvertiseListenerImpl component in mod_cluster's core multicast UDP handler can be permanently crashed by a single crafted datagram, affecting Red Hat JBoss Enterprise Application Platform 7 and 8, JBoss Web Server 5 through 7, and Red Hat Single Sign-On 7. An unauthenticated attacker with adjacency to the mod_cluster multicast group can silently terminate the advertise listener thread, causing the affected node to stop receiving cluster topology updates until manually restarted - with no runtime indication of failure since isListening() continues returning true. No public exploit is identified at time of analysis, and this CVE is not listed in the CISA KEV catalog based on available data.
Undertow's HTTP response header writing path silently truncates 16-bit Unicode characters to 8-bit bytes via a narrowing cast in the `writeString()` method, enabling remote unauthenticated attackers to inject ASCII control characters or special symbols into response headers when an application passes unsanitized user-controlled input into those headers. Affected Red Hat distributions include RHEL 8/9/10, JBoss EAP 7, Red Hat Build of Apache Camel for Spring Boot 4, and Red Hat Single Sign-On 7, as reported by Red Hat via Bugzilla #2516038. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
HTTP request smuggling in Undertow's ChunkReader component enables unauthenticated remote attackers to inject out-of-sync requests, bypassing upstream security controls such as authentication layers or reverse-proxy ACLs. Affected deployments include JBoss EAP 7, WildFly, Red Hat Enterprise Linux 8/9/10, Red Hat Data Grid 8, Red Hat Fuse 7, Red Hat Single Sign-On 7, and several Apache Camel-based Red Hat products. No confirmed active exploitation or public proof-of-concept has been identified at time of analysis; the CVSS 5.3 Medium score reflects limited direct impact, though real-world risk in proxy-fronted architectures is meaningfully higher than the score alone suggests.
Unrestricted archive upload in WildFly Core enables authenticated 'deployer' role users to deploy malicious Java archives via HTTP POST requests, potentially achieving arbitrary file reads and further system compromise. Affected products span multiple Red Hat enterprise offerings including JBoss EAP 7 and 8, Red Hat Fuse 7, Process Automation 7, and Single Sign-On 7, all of which embed wildfly-core as a foundational dependency. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Denial of service in WildFly Core (and downstream Red Hat middleware products) allows a remote administrative user to render a server permanently unrecoverable by injecting a malformed payload into the Inet Address field of the Management Model. The injected payload is persisted to standalone.xml, corrupting the configuration file and preventing normal server restart without manual intervention. No public exploit code has been identified at time of analysis, and the vulnerability is limited to users with administrative credentials, reducing its real-world blast radius despite the high availability impact.
Path traversal in WildFly's domain mode LocalFileRepository exposes arbitrary files readable by the Domain Controller process to attackers who have already obtained or compromised a slave host controller. The flaw resides in the wildfly-core/deployment-repository component, where getFile() and getConfigurationFile() fail to canonicalize or bound-check caller-supplied paths before resolving them on disk, enabling directory traversal sequences to escape the configured repository root. No active exploitation is confirmed (not listed in CISA KEV) and no public exploit code has been identified, but successful exploitation yields high-confidence access to sensitive artifacts including keystores, credentials, and configuration files.
Access-control bypass in Keycloak (fixed in 26.5.3) lets a disabled user account still obtain valid tokens through the JWT authorization grant preview feature. When that feature is enabled, Keycloak omits the account-enabled check during JWT authorization grant processing, so a low-privileged remote attacker who can present a valid assertion token from an external identity provider can mint a JWT for an account an administrator has explicitly disabled, regaining access to protected resources. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Cross-site scripting in Jastow - the JSP implementation layer embedded within Red Hat JBoss Enterprise Application Platform alongside Undertow - allows unauthenticated remote attackers to inject and execute malicious scripts when a specific combination of configurations permits unescaped characters to pass through URL processing. Affected deployments span JBoss EAP 7, EAP 8, the Expansion Pack, and linked products such as Red Hat Single Sign-On 7 that share this component. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Privilege escalation in Keycloak allows a limited administrator to become a full realm administrator by importing users with realm-admin role mappings via the POST /admin/realms/{realm}/partialImport endpoint, bypassing Fine-Grained Admin Permissions (FGAP). Exploitation requires a high-privilege authenticated user, and while a proof-of-concept exploit exists, the EPSS score is very low (0.03%) and there is no evidence of active exploitation.
Remote code execution in Red Hat Apache Camel Infinispan component allows low-privileged attackers to execute arbitrary code via unsafe deserialization in ProtoStream remote aggregation repository. Exploiting this vulnerability requires network access and low-privilege credentials but grants full system compromise affecting confidentiality, integrity, and availability. The attack complexity is rated high (AC:H), suggesting specific configuration or timing requirements. No active exploitation confirmed at time of analysis (not in CISA KEV), and public exploit code status is unknown.
HTTP request smuggling in Undertow (the embedded web server underpinning JBoss EAP, Red Hat Data Grid, and Apache Camel for Spring Boot) allows remote unauthenticated attackers to bypass front-end security controls by prepending whitespace to header lines. Undertow strips leading spaces from the first header line in violation of RFC 7230, creating a parser discrepancy between upstream proxies and the application server. No public exploit identified at time of analysis, and EPSS sits at 0.13% (32nd percentile), but the CVSS 9.1 and broad Red Hat middleware exposure make this a high-value target for chained attacks.
HTTP request smuggling in Undertow allows remote unauthenticated attackers to send `\r\r\r` as a header block terminator, which can desynchronize parsing when Undertow sits behind specific intermediaries such as older Apache Traffic Server or Google Cloud Classic Application Load Balancer. The flaw affects numerous Red Hat distributions of Undertow (JBoss EAP 7/8, Data Grid 8, Fuse 7, Camel for Spring Boot 4, RHEL 8/9/10) and carries a CVSS 9.1, though EPSS is only 0.04% and there is no public exploit identified at time of analysis.
HTTP request smuggling in Red Hat Undertow allows remote unauthenticated attackers to bypass front-end security controls by exploiting parsing discrepancies between Undertow and upstream proxies when handling crafted header names. The flaw (CWE-444) affects Undertow embedded in multiple Red Hat products including JBoss EAP 7/8, Data Grid 8, Fuse 7, and Apache Camel for Spring Boot 4, with Red Hat issuing patches via RHSA-2026:25125 and RHSA-2026:25126. There is no public exploit identified at time of analysis and EPSS is low (0.10%), but CVSS 9.1 and SSVC 'total' technical impact warrant prompt patching of internet-facing deployments.
Keycloak allows authenticated administrators with manage-clients permission to escalate privileges to manage-permissions level, enabling unauthorized control over roles, users, and administrative functions within a realm. Red Hat Build of Keycloak, JBoss Enterprise Application Platform 8, and Red Hat Single Sign-On 7 are affected when admin permissions are enabled at the realm level. The vulnerability requires high-privilege authentication but carries medium CVSS severity (6.5) due to confidentiality and integrity impact without availability compromise.
