{"id":"CVE-2026-79650","summary":"Apache CXF: OIDC RP Open Redirect","details":"Apache CXF’s OIDC relying-party component could redirect users to an attacker-controlled URL after successful authentication. The issue occurs because attacker-controlled state parameters are preserved and later used as redirect targets without validating that the final decoded URI belongs to the RP’s origin. Both directly encoded and double-encoded external URLs can trigger the issue, depending on which validation path is used. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.","modified":"2026-10-24T10:52:09.953422885Z","published":"2026-10-09T10:18:21.966Z","database_specific":{"cna_assigner":"apache","cwe_ids":["CWE-601"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79650.json","unresolved_ranges":[{"extracted_events":[{"range":[{"introduced":"4.2.0"},{"fixed":"4.2.4"},{"introduced":"4.0.0"},{"fixed":"4.1.9"},{"fixed":"3.6.13"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/10/09/7"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79650.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread.html/xj0x1r617j1z8jtyypngvwhckb3o205h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-79650"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/cxf","events":[{"introduced":"0"},{"fixed":"8999af05d26ef2e63dc4c77a798595e2a53435ad"},{"introduced":"02310e95fe74c0c031f540f3284e4a9bd856ced2"},{"fixed":"043829b193a6ead389864e636a07ddf6bfa2ca8a"},{"introduced":"04ccbfd709eef8f4af53d6237514fbe9db7ea81f"},{"fixed":"5e324f121104cc76af1b8f3ec0d1a20ef9e98c3b"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"3.6.13"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:apache:cxf:*:*:*:*:*:*:*:*"},{"range":[{"introduced":"4.0.0"},{"fixed":"4.1.9"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:apache:cxf:*:*:*:*:*:*:*:*"},{"cpe":"cpe:2.3:a:apache:cxf:*:*:*:*:*:*:*:*","range":[{"introduced":"4.2.0"},{"fixed":"4.2.4"}],"source":"CPE_RANGE"}]}}],"versions":["cxf-3.6.12","cxf-4.1.8","cxf-4.2.3","cxf-4.1.7","cxf-4.2.2","cxf-3.6.11","cxf-4.1.6","cxf-4.2.1","cxf-3.6.10","cxf-4.1.5","cxf-4.2.0","cxf-3.6.9","cxf-4.1.4","cxf-3.6.8","cxf-4.1.3","cxf-3.6.7","cxf-4.1.2","cxf-3.6.6","cxf-4.1.1","cxf-4.1.0","cxf-3.6.5","cxf-3.6.4","cxf-3.6.3","cxf-4.0.4","cxf-4.0.3","cxf-3.6.2","cxf-4.0.2","cxf-3.6.1","cxf-4.0.1","cxf-3.6.0","cxf-4.0.0","cxf-3.5.0","cxf-3.4.1","cxf-3.4.0","cxf-3.3.3","cxf-3.3.2","cxf-3.3.1","cxf-3.3.0","cxf-3.2.5","cxf-3.2.4","cxf-3.2.3","cxf-3.2.2","cxf-3.2.1","cxf-3.2.0","cxf-3.1.4","cxf-3.1.3","cxf-3.1.2","cxf-3.1.1","cxf-3.1.0","cxf-3.0.0","cxf-3.0.0-milestone2","cxf-2.7.2","cxf-2.7.1","cxf-2.7.0","cxf-2.6.1","cxf-2.6.0","cxf-2.5.1","cxf-2.5.0","cxf-2.4.0","cxf-2.3.0","cxf-2.2.2","cxf-2.2.1","cxf-2.2","cxf-2.1.2","cxf-2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-79650.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
