This functionality improperly checked permissions, allowing any user with Overall/Read access to Jenkins to connect to any web server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery.","published":"2017-10-05T01:29:04.000Z","lastModified":"2026-06-17T00:58:43.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":6.3,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"},"cwe":["CWE-352"],"affected":["jenkins/github branch source"],"epss":{"score":0.00641,"percentile":0.50479,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.64%).
