{"schema":"threatline.record/2","record":{"id":"CVE-2026-94197","aliases":[],"summary":"NGINX Ingress Controller vulnerability","details":"An authentication and authorization bypass vulnerability exists in F5 NGINX Kubernetes Ingress Controller (NIC) when configured with the `ExternalAuth` policy or Ingress external authentication. Client-supplied X-Forwarded-Prefix, X-Forwarded-URI, X-Original-URI, and X-Forwarded-Method routing and method headers are forwarded unsanitized into the internal authentication subrequest (handled by the NGINX auth_request directive). As a result, an unauthenticated, remote attacker may spoof request attributes evaluated by the external authentication provider. \n\nImpact:\nThis vulnerability may allow remote attackers \n\nunauthenticated\n\n access to protected \n\npaths. There is no control plane exposure; this is a data plane issue only.\n\n\n\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","categories":["Web servers"],"product":"NGINX Ingress Controller","vendor":"F5","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94197","source_modified_at":"2026-10-15T16:43:46.770Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"NGINX Ingress Controller","vendor":"F5","versions":[{"lessThan":"5.7.0","status":"affected","version":"5.5.0","versionType":"custom"}],"defaultStatus":"unknown"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94197","source_modified_at":"2026-10-15T16:43:46.770Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"NGINX Ingress Controller","ecosystem":null},"version":"5.7.0","basis":"first unaffected version stated in the CVE record"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00393,"percentile":0.32327,"score_date":"2026-10-23"},"published_at":"2026-10-14T14:40:28.582Z","modified_at":"2026-10-15T16:43:46.770Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-94197","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T16:43:46.770Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-94197","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://my.f5.com/manage/s/article/K000162611","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-15T15:53:41.365707Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-15T16:43:46.770Z","content_hash":"5a554d6ddf30a13cc71d0f37bf131c1aebac2fd141f274f1dab93f5aec0fb084"}}
