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.","epss":{"date":"2026-11-06","percentile":0.55683,"score":0.00767},"exploits":[],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},{"score":7.5,"severity":"high","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"}],"modifiedAt":1793985604727,"publishedAt":1789741091431,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:69440"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:69470"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:70257"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:83612"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95759"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95760"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95762"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95887"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-93565"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536952"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:69440"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:69470"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:70257"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:83612"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95759"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95760"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95762"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95887"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-93565"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536952"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"See https://github.com/netty/netty/security/advisories/GHSA-h75q-xqrh-59rf for fixed versions and remediation guidance."}],"revision":"36a16f0dc3cc7bba10693ecf0c46df1e411a375f3841963b07fea6bdf377a613","sources":[{"modifiedAt":1793985141613,"name":"CNA: redhat","retrievedAt":1793986138025,"url":"https://www.cve.org/CVERecord?id=CVE-2026-93565"},{"modifiedAt":1793985604727,"name":"NVD","retrievedAt":1793989809728,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93565"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793986141634,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93565"}],"ssvc":{"assessedAt":1790020114585,"automatable":"yes","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Io.netty/netty-codec-http: netty rtspdecoder method-token smuggling via trailing control byte","updatedAt":1793989809728}
