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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://lists.apache.org/thread/zm6t8skkkskjwk1881l4m4n0l7dqclzo","http://www.openwall.com/lists/oss-security/2026/05/01/7"],"products":["apache:neethi"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-42403","score":0.00763,"percentile":0.55121,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-2hfh-9h53-qc24","url":"https://osv.dev/vulnerability/GHSA-2hfh-9h53-qc24","summary":"Apache Neethi does not properly detect circular references in policy definitions.","modified":"2026-09-10T03:50:45.338019137Z","packages":[{"ecosystem":"Maven","name":"org.apache.neethi:neethi","purl":"pkg:maven/org.apache.neethi/neethi","ranges":["<3.2.2"],"fixed":["3.2.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
