Description OSIDB Bzimport 2026-10-28 17:11:35 UTC
Jenkins 2.587 and earlier, LTS 2.580.1 and earlier follows symbolic links when copying the directory of an item being renamed, allowing attackers with Item/Create and Item/Configure permission to read arbitrary files on the Jenkins controller file system.
