This vulnerability allows a remote attacker to bypass `Transfer-Encoding` header validation by splitting the `Transfer-Encoding` field across multiple headers, with the last field containing a non-final transfer coding like `gzip` or `deflate`. This bypass can lead to HTTP request smuggling, enabling attackers to bypass security controls, desynchronize request processing, or cause requests to be processed in an unintended context.","epss":{"date":"2026-11-05","percentile":0.59689,"score":0.00896},"exploits":[],"kev":null,"metrics":[{"score":6.5,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},{"score":6.5,"severity":"medium","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793963840503,"publishedAt":1789742640077,"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-2026:83612"},{"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":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-93573"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536964"},{"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-2026:83612"},{"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/security/cve/CVE-2026-93573"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536964"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"See https://github.com/netty/netty/security/advisories/GHSA-3jrc-fchc-59pw for fixed versions and remediation guidance."}],"revision":"6b90a9dced3f6b63e1e6a43b11d178c285a8f707764efeddf6e88c67f4d4c2da","sources":[{"modifiedAt":1793960758962,"name":"CNA: redhat","retrievedAt":1793963463632,"url":"https://www.cve.org/CVERecord?id=CVE-2026-93573"},{"modifiedAt":1793963840503,"name":"NVD","retrievedAt":1793967444036,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93573"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793945306707,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93573"}],"ssvc":{"assessedAt":1789748394114,"automatable":"yes","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Io.netty/netty-codec-http: netty split transfer-encoding fields bypass final-chunked validation and enable request smuggling","updatedAt":1793967444036}
