Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Jenkins Pipeline: Groovy Libraries Plugin versions 797.v90ea_a_9b_e45a_0 and earlier (Maven package io.jenkins.plugins:pipeline-groovy-lib) do not prohibit symbolic links in shared libraries. An attacker who can control the content of a library used by a Pipeline job can read arbitrary files on the Jenkins controller filesystem. Upgrade to version 798.v5cc688825312, which prohibits symbolic links in shared libraries.
