{"schema_version": "1.6.1", "id": "CVE-2026-42403", "summary": "Circular Policy Reference Infinite Loop", "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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "0"}, {"fixed": "3.2.2"}]}]}], "references": [{"type": "WEB", "url": "https://lists.apache.org/thread/zm6t8skkkskjwk1881l4m4n0l7dqclzo"}]}
