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.","state":0,"publishedAt":"2026-09-30T12:25:28.399+00:00","modifiedAt":"2026-09-30T13:17:31.672+00:00","affected":[{"ecosystem":"https://repo.maven.apache.org/maven2","name":"org.apache.wss4j:wss4j-ws-security-common","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache WSS4J\",\n                    \"packageURL\": \"pkg:maven/org.apache.wss4j/wss4j-ws-security-common\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.0.0\",\n                            \"lessThan\": \"4.0.2\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"3.0.0\",\n                            \"lessThan\": \"3.0.6\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"2.4.4\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://repo.maven.apache.org/maven2\",\n                    \"packageName\": \"org.apache.wss4j:wss4j-ws-security-common\"\n                }"}],"metrics":[],"references":["https://lists.apache.org/thread.html/sdf0fsphkg4qbj7nh2brjgwvcmd67hct"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-95616","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-95616","identifiers":["CVE-2026-95616"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
