{"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":"2026-08-12T03:30:42.074779475Z","published":"2026-05-01T08:38:16.035Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42403.json","unresolved_ranges":[{"extracted_events":[{"fixed":"3.2.2"}],"source":"AFFECTED_FIELD"}],"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":"2351df23093e1bd4b2d2c8f9630e95e929a5de4e"}],"database_specific":{"cpe":"cpe:2.3:a:apache:neethi:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"3.2.2"}],"source":"CPE_RANGE"}}],"versions":["neethi-3.2.1","neethi-3.2.0","neethi-3.0.2@1310942","neethi-3.0.1@1145220","3.0.0@1088365","2.0.5@787316","2.0.4@649060","2.0.3@646794","2_0_2@556647","2_0_2@553081","2_0_1@529482","2_0@474163","1_0_1@398892","neethi-3.0.2@398891","neethi-3.0.1@398891","3.0.0@398891","2_0_2@398891-","2_0_2@398891","2_0_1@398891","2_0@398891","2.0.5@398891","2.0.4@398891","2.0.3@398891","1_0_1@398891","1_01_RC@392334","neethi-3.0.2@388355","neethi-3.0.1@388355","3.0.0@388355","2_0_2@388355-","2_0_2@388355","2_0_1@388355","2_0@388355","2.0.5@388355","2.0.4@388355","2.0.3@388355","1_0_1@388355","1_01_RC@388355","1_0@388063","0_90@383288","neethi-3.0.2@374083","neethi-3.0.1@374083","3.0.0@374083","2_0_2@374083--","2_0_2@374083-","2_0_1@374083","2_0@374083","2.0.5@374083","2.0.4@374083","2.0.3@374083","1_0_1@374083","1_0@374083","1_01_RC@374083","0_90@374083","2_0_2@374083","neethi-3.0.2@331547","neethi-3.0.1@331547","3.0.0@331547","2_0_2@331547--","2_0_2@331547-","2_0_2@331547","2_0_1@331547","2_0@331547","2.0.5@331547","2.0.4@331547","2.0.3@331547","1_0_1@331547","1_0@331547","1_01_RC@331547","0_90@331547"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-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"}]}
