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."}], "lastModified": "2026-05-01T18:08:21.653", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:neethi:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "919C93DA-F5F7-4F2B-AD9B-C3BD46065619", "versionEndExcluding": "3.2.2"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
