{"id":"CVE-2026-42403","summary":"Apache Neethi: 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.","aliases":["GHSA-2hfh-9h53-qc24"],"modified":"2026-09-04T11:45:44.783846314Z","published":"2026-05-01T08:38:16.035Z","related":["CGA-m885-89wq-4x34"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42403.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"3.2.2"}]}],"cna_assigner":"apache","cwe_ids":["CWE-400"]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/05/01/7"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42403.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/zm6t8skkkskjwk1881l4m4n0l7dqclzo"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42403"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/ws-neethi","events":[{"introduced":"0"},{"fixed":"768b735078930d4f02ba5e31fae8458e3b8a6d01"}],"database_specific":{"cpe":"cpe:2.3:a:apache:neethi:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"3.2.2"}],"source":"CPE_RANGE"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-42403.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"}]}
