Jenkins Pipeline: Groovy Libraries Plugin 797.v90ea_a_9b_e45a_0 and earlier does not prohibit symbolic links in shared libraries. If an attacker can control the contents of a shared library that is used by a Jenkins Pipeline job, they can include symlinks that resolve to files outside the intended library workspace and cause the Pipeline processing to read arbitrary files from the Jenkins controller filesystem. The issue is tracked as SECURITY-3727 / CVE-2026-48921.
