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.","state":0,"publishedAt":"2026-09-10T15:35:12.851+00:00","modifiedAt":"2026-09-11T20:33:29.626+00:00","affected":[{"ecosystem":"Vendor product","name":"traefik","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"traefik\",\n                    \"product\": \"traefik\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.8.2, < 2.11.56\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.0.0, < 3.7.12\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/traefik/traefik/security/advisories/GHSA-7ghq-v6jf-g56c","https://github.com/traefik/traefik/pull/13717","https://github.com/traefik/traefik/commit/a8d0bc425859dde7481a6c9a324e610b81d754d0","https://github.com/traefik/traefik/releases/tag/v2.11.56","https://github.com/traefik/traefik/releases/tag/v3.7.12"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-88012","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-88012","identifiers":["CVE-2026-88012"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
