From 2.8.2 until 2.11.56 and 3.7.12, HTTP/3 entrypoints do not apply entryPoints..transport.respondingTimeouts.readTimeout because the timeout is enforced on a TCP connection and the HTTP/3 server has no corresponding QUIC stream deadline. An unauthenticated client can use a slow request body, trickling data indefinitely while holding a request and an upstream connection open and exhausting backends with bounded connection pools. This issue is fixed in 2.11.56 and 3.7.12.","published":"2026-09-10T16:18:08.067","modified":"2026-09-10T16:18:08.067","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/traefik/traefik/commit/a8d0bc425859dde7481a6c9a324e610b81d754d0","label":"traefik/traefik@a8d0bc4"},"references":[{"type":"WEB","url":"https://github.com/traefik/traefik/commit/a8d0bc425859dde7481a6c9a324e610b81d754d0"},{"type":"WEB","url":"https://github.com/traefik/traefik/pull/13717"},{"type":"WEB","url":"https://github.com/traefik/traefik/releases/tag/v2.11.56"},{"type":"WEB","url":"https://github.com/traefik/traefik/releases/tag/v3.7.12"},{"type":"WEB","url":"https://github.com/traefik/traefik/security/advisories/GHSA-7ghq-v6jf-g56c"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T16:18:08.067"}}
