{"id":"CVE-2026-42404","aliases":["GHSA-287c-fxr7-3w6c"],"url":"https://o3.security/vulnerability/CVE-2026-42404","summary":"Apache Neethi: Unrestricted HTTP Redirect Following in Policy References","details":"Apache Neethi does not impose any restrictions on URIs when manually fetching remote policy references through the PolicyReference API. When an application explicitly calls the API to retrieve a policy from a remote URI, an outbound request is made for arbitrary protocols and internal IP adddresses. From 3.2.2, only http or https URIs are allowed, and link-local/multicast/any-local addresses are forbidden.\n\nUsers are recommended to upgrade to version 3.2.2, which fixes this issue.","published":"2026-05-01T09:46:49.958Z","modified":"2026-09-11T11:46:18.571056847Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":{"score":0.00497,"percentile":0.40282,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.neethi:neethi","fixedVersion":"3.2.2"}],"fix":null,"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/05/01/8"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42404.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/zdspnt64zznyjyn648553kptx69w23oq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42404"},{"type":"PACKAGE","url":"https://github.com/apache/ws-neethi"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T11:46:18.571056847Z"}}
