{"schema":"threatline.record/2","record":{"id":"CVE-2026-95616","aliases":[],"summary":"Apache WSS4J: Unauthenticated denial of service via integer overflow in DER parsing of X.509 certificate extensions","details":"An integer overflow in WSS4J's DER bounds check lets an oversized allocation pass validation. An unauthenticated attacker can send a SOAP message carrying an X.509 certificate whose SubjectKeyIdentifier extension declares a length of 0x7FFFFFFF; WSS4J decodes this while resolving the signature's key reference, before the message is authenticated, so an eleven-byte extension triggers a 2 GB allocation. Repeated requests exhaust server memory.\nUsers are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.","categories":["Unclassified"],"product":"Apache WSS4J","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95616","source_modified_at":"2026-09-30T13:17:31.672Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Apache WSS4J","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"4.0.0","lessThan":"4.0.2","versionType":"semver"},{"status":"affected","version":"3.0.0","lessThan":"3.0.6","versionType":"semver"},{"status":"affected","version":"0","lessThan":"2.4.4","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95616","source_modified_at":"2026-09-30T13:17:31.672Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Apache WSS4J","ecosystem":null},"version":"4.0.2","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95616","source_modified_at":"2026-09-30T13:17:31.672Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Apache WSS4J","ecosystem":null},"version":"3.0.6","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95616","source_modified_at":"2026-09-30T13:17:31.672Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Apache WSS4J","ecosystem":null},"version":"2.4.4","basis":"first unaffected version stated in the CVE record"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00409,"percentile":0.34046,"score_date":"2026-10-23"},"published_at":"2026-09-30T12:25:28.399Z","modified_at":"2026-09-30T13:17:31.672Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-95616","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T13:17:31.672Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-95616","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/sdf0fsphkg4qbj7nh2brjgwvcmd67hct","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-30T12:43:35.342143Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T13:17:31.672Z","content_hash":"19dd7ebfc7a468f537b8b7d807028b5476cb78500f79cde88ae59d280e525daf"}}
