{"schemaVersion":3,"id":"CVE-2026-79650","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-10-09T10:18:21.966Z","modified":"2026-10-15T16:20:11.251Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.1,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00202,"percentile":0.09538,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-10T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00202,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00202,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00202,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00202,"percentile":0.09538}],"last30":[{"date":"2026-10-10T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00195,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00202,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00202,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00202,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00202,"percentile":0.09538}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site ('Open Redirect')","description":"The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":"Low","url":"https://cwe.mitre.org/data/definitions/601.html"}],"affected":[{"vendor":"apache software foundation","product":"apache cxf","name":"Apache CXF","label":"apache cxf","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≥ 4.2.0, < 4.2.4","noFixRecorded":false,"fixedIn":null},{"text":"≥ 4.0.0, < 4.1.9","noFixRecorded":false,"fixedIn":null},{"text":"< 3.6.13","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 4.2.0, < 4.2.4 | ≥ 4.0.0, < 4.1.9 | < 3.6.13","eol":null,"hubHref":"/vendor/apache_software_foundation/apache_cxf"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://lists.apache.org/thread.html/xj0x1r617j1z8jtyypngvwhckb3o205h","label":"lists.apache.org/thread.html/xj0x1r617j1z8jtyypngvwhckb3o205h","hostname":"lists.apache.org","tags":["Vendor Advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2026/10/09/7","label":"www.openwall.com/lists/oss-security/2026/10/09/7","hostname":"www.openwall.com","tags":[]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-09T10:18:21.966Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-15T16:20:11.251Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":24,"level":"low","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T03:38:20.457Z","stale":false,"partial":false}}
