{"id":"GHSA-2hfh-9h53-qc24","summary":"Apache Neethi does not properly detect circular references in policy definitions.","details":"Apache Neethi does not properly detect circular references in policy definitions. When a WS-Policy document contains circular policy references (where Policy A references Policy B which references Policy A), the policy normalization process can enter an infinite loop or cause excessive recursion, leading to a stack overflow or application hang. An attacker can craft malicious policy documents with circular references to cause a Denial of Service condition\n\nUsers are recommended to upgrade to version 3.2.2, which fixes this issue.","aliases":["CVE-2026-42403"],"modified":"2026-07-17T21:12:16.130715607Z","published":"2026-05-01T09:30:25Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-05-07T02:39:24Z","nvd_published_at":"2026-05-01T09:16:17Z","cwe_ids":["CWE-400"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42403"},{"type":"PACKAGE","url":"https://github.com/apache/ws-neethi"},{"type":"WEB","url":"https://lists.apache.org/thread/zm6t8skkkskjwk1881l4m4n0l7dqclzo"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/05/01/7"}],"affected":[{"package":{"name":"org.apache.neethi:neethi","ecosystem":"Maven","purl":"pkg:maven/org.apache.neethi/neethi"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.2"}]}],"versions":["2.0","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","3.0.0","3.0.1","3.0.2","3.0.3","3.1.0","3.1.1","3.2.0","3.2.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-2hfh-9h53-qc24/GHSA-2hfh-9h53-qc24.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
