{"id":"CVE-2026-119572","summary":"Traefik 3.7.0-ea.1 before 3.7.15 mTLS Bypass via Ingress NGINX Provider","details":"Traefik from 3.7.0-ea.1 before 3.7.15 contains an authentication bypass vulnerability in the Kubernetes Ingress NGINX provider that silently disables mTLS configured via the auth-tls-secret annotation. When another Ingress declares a path on the same host without matching auth-tls settings, Traefik falls back to default TLS options, letting unauthenticated attackers reach backends requiring client certificates.","aliases":["GHSA-p8wx-ph99-xgcr"],"modified":"2026-11-07T02:30:36.427650079Z","published":"2026-10-30T13:18:11.594Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-287"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/119xxx/CVE-2026-119572.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/119xxx/CVE-2026-119572.json"},{"type":"ADVISORY","url":"https://github.com/traefik/traefik/security/advisories/GHSA-p8wx-ph99-xgcr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119572"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/traefik-3.7.0-ea.1-before-3.7.15-mtls-bypass-via-ingress-nginx-provider"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/traefik/traefik","events":[{"introduced":"67c64ed9b25fbb90f1086977a62827133a7aa01b"},{"fixed":"351a5ab1e884a6be95d02997016cbb2751106bc0"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"3.7.0-ea.1"},{"fixed":"3.7.15"}]},{"range":[{"introduced":"3.7.0-ea.1"},{"fixed":"3.7.15"}],"source":"DESCRIPTION"}]}}],"versions":["v3.7.14","v3.7.13","v3.7.12","v3.7.11","v3.7.10","v3.7.9","v3.7.8","v3.7.7","v3.7.6","v3.7.5","v3.7.4","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.7.0-rc.3","v3.7.0-rc.2","v3.7.0-rc.1","v3.7.0-ea.3","v3.7.0-ea.1","v3.7.0-ea.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-119572.json"}}],"schema_version":"1.9.2","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"}]}
