Red Hat Build Of Apache Camel For Spring Boot 4
Monthly
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.
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.
