{"schema":"threatline.record/2","record":{"id":"CVE-2026-97205","aliases":[],"summary":"NGINX ngx_http_core_module vulnerability","details":"NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_core_module module. When asynchronous file I/O (AIO) is enabled in certain configurations, processing a Server Side Includes (SSI) page containing “include virtual” commands may trigger a Use-After-Free (UAF) in the NGINX worker process. This may cause memory corruption or a worker process crash. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.\n\nImpact:\nThis vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system, corrupt its memory, or possibly trigger code execution. 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 Plus","vendor":"F5","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97205","source_modified_at":"2026-10-15T10:31:15.547Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"NGINX Plus","vendor":"F5","versions":[{"lessThan":"37.1.0.1","status":"affected","version":"37.1.0","versionType":"custom"},{"lessThan":"37.0.5.1","status":"affected","version":"37.0.0","versionType":"custom"},{"lessThan":"*","status":"affected","version":"R36","versionType":"custom"},{"lessThan":"*","status":"affected","version":"R35","versionType":"custom"},{"lessThan":"*","status":"affected","version":"R34","versionType":"custom"},{"lessThan":"*","status":"affected","version":"R33","versionType":"custom"}],"defaultStatus":"unknown"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97205","source_modified_at":"2026-10-15T10:31:15.547Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"NGINX Open Source","vendor":"F5","versions":[{"lessThan":"1.31.7","status":"affected","version":"1.31.0","versionType":"custom"},{"lessThan":"1.30.6","status":"affected","version":"1.30.0","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97205","source_modified_at":"2026-10-15T10:31:15.547Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"NGINX Plus","ecosystem":null},"version":"37.1.0.1","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97205","source_modified_at":"2026-10-15T10:31:15.547Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"NGINX Plus","ecosystem":null},"version":"37.0.5.1","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97205","source_modified_at":"2026-10-15T10:31:15.547Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"NGINX Open Source","ecosystem":null},"version":"1.31.7","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97205","source_modified_at":"2026-10-15T10:31:15.547Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"NGINX Open Source","ecosystem":null},"version":"1.30.6","basis":"first unaffected version stated in the CVE record"}],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00484,"percentile":0.40788,"score_date":"2026-10-23"},"published_at":"2026-10-14T14:40:27.487Z","modified_at":"2026-10-15T10:31:15.547Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97205","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T10:31:15.547Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97205","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/K000162608","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-15T03:57:01.124115Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-15T10:31:15.547Z","content_hash":"976ff2d5cb6bcf87c4e66efe60c3943386f984e42814bc1fa376eb121a24e4b9"}}
