The `RtspMethods.valueOf()` function incorrectly strips trailing control bytes from method tokens in Real-Time Streaming Protocol (RTSP) requests. A remote attacker can exploit this by sending a specially crafted RTSP request, leading to method-token smuggling. This vulnerability allows an attacker to bypass method-based access controls and can also be used to launder malicious requests through Netty-based RTSP proxies, making them appear legitimate to backend systems.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat AMQ Broker 7, Red Hat AMQ Clients, Red Hat build of Apache Camel 4 for Quarkus 3, Red Hat build of Apache Camel for Spring Boot 4, Red Hat build of Apicurio Registry 3, Red Hat build of Debezium 3, … · no fix planned: Red Hat Fuse 7, Red Hat JBoss Enterprise Application Platform 7, Red Hat Single Sign-On 7, Red Hat AMQ Broker 7, … · updated 2026-10-09 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-93565.json)\n- **RHSA-2026:70257** · Red Hat · fixed in: Red Hat Build of Apache Camel 3.33.3.SP2 · released 2026-09-22 · [advisory](https://access.redhat.com/errata/RHSA-2026:70257)\n- **RHSA-2026:69470** · Red Hat · fixed in: Red Hat build of Quarkus 3.27.5.SP2 · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69470)\n- **RHSA-2026:69440** · Red Hat · fixed in: Red Hat build of Quarkus 3.33.3.SP2 · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69440)","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
