{"id":"CVE-2026-114636","summary":"Traefik v3.7.13 Authentication Bypass via ssl-passthrough Ingress HTTP Router","details":"Traefik v3.7.13 before v3.7.14 contains an access-control bypass in the Kubernetes Ingress NGINX provider, where the HTTP router generated for ssl-passthrough Ingresses on non-TLS entry points never applies the Ingress's access-control annotations. Unauthenticated attackers reaching the HTTP entry point with the Ingress host can access backends protected by auth-type, auth-url, or whitelist-source-range annotations, with nothing logged.","aliases":["GHSA-qvj7-gq9c-hp7q"],"modified":"2026-10-22T10:46:14.405799157Z","published":"2026-10-22T01:43:37.186Z","database_specific":{"cwe_ids":["CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114636.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114636.json"},{"type":"ADVISORY","url":"https://github.com/traefik/traefik/security/advisories/GHSA-qvj7-gq9c-hp7q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114636"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/traefik-3.7.13-authentication-bypass-via-ssl-passthrough-ingress-http-router"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/traefik/traefik","events":[{"introduced":"fc92cc118a0557a029c7019d5ee06665127b0f13"},{"fixed":"3bd7aa32e1b6c41166575529a10fb2346d9eaa2e"}],"database_specific":{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"3.7.13"},{"fixed":"3.7.14"}],"source":"AFFECTED_FIELD"}]}}],"versions":["v3.7.13"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-114636.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N"}]}
