{"schema":"threatline.record/2","record":{"id":"CVE-2026-86463","aliases":[],"summary":"Apache CXF: FIQL Query Parser Denial of Service","details":"Apache CXF's FIQL query parser has a vulnerability in how it searches for operators in query expressions. The search pattern can get stuck trying many combinations when it encounters a long string without an operator, causing the parser to consume excessive CPU time. An attacker can send a crafted query to make the server use up CPU resources, potentially slowing down or stopping other requests. The fix was to limit FIQL expressions to 4 KiB by default, preventing attackers from sending extremely long inputs while still allowing normal queries.\n\nUsers are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.","categories":["Unclassified"],"product":"Apache CXF","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-86463","source_modified_at":"2026-10-15T16:26:53.196Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Apache CXF","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"4.2.0","lessThan":"4.2.4","versionType":"semver"},{"status":"affected","version":"4.0.0","lessThan":"4.1.9","versionType":"semver"},{"status":"affected","version":"0","lessThan":"3.6.13","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-86463","source_modified_at":"2026-10-15T16:26:53.196Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Apache CXF","ecosystem":null},"version":"4.2.4","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-86463","source_modified_at":"2026-10-15T16:26:53.196Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Apache CXF","ecosystem":null},"version":"4.1.9","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-86463","source_modified_at":"2026-10-15T16:26:53.196Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Apache CXF","ecosystem":null},"version":"3.6.13","basis":"first unaffected version stated in the CVE record"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00448,"percentile":0.3798,"score_date":"2026-10-23"},"published_at":"2026-10-09T10:18:42.008Z","modified_at":"2026-10-15T16:26:53.196Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-86463","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T16:26:53.196Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-86463","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://lists.apache.org/thread.html/mv5qfmd27gkbvt3k6by9db5bolrsbgy1","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T16:26:44.797809Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T16:26:53.196Z","content_hash":"e1cb53f6775fe9cee8d85444e6206b468e556e747116d81a0b482bc4507305f8"}}
