6.5 mediumCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:NCVE-2021-21683
Medium (6.5) in jenkins jenkins. EPSS 2.2% chance of exploitation in the next 30 days. Fixed in org.jenkins-ci.main:jenkins-core 2.303.2, 2.315.
The file browser in Jenkins 2.314 and earlier, LTS 2.303.1 and earlier may interpret some paths to files as absolute on Windows, resulting in a path traversal vulnerability allowing attackers with Overall/Read permission (Windows controller) or Job/Workspace permission (Windows agents) to obtain the contents of arbitrary files.
