Jenkins Pipeline: Groovy Libraries Plugin vulnerabilities

Jenkins Pipeline: Groovy Libraries Plugin 805.va_fc79344957d and earlier does not restrict the library path provided to the library Pipeline step to a relative path inside the SCM checkout, and follows symbolic links to locations outside of the SCM checkout when retrieving the library, resulting in a path traversal vulnerability, allowing attackers able to configure Pipelines to read files in a resources directory and to delete files in a test directory on the Jenkins controller file system.

The Groovy Libraries Plugin in Jenkins Pipeline version 797.v90ea_a_9b_e45a_0 and earlier does not prohibit the use of symbolic links in shared libraries. This allows attackers who can control the content of a library used by a Pipeline job to read arbitrary files on the Jenkins controller filesystem.

A cross-site request forgery (CSRF) vulnerability in Jenkins Pipeline: Groovy Libraries Plugin 798.v5cc688825312 and earlier allows attackers to delete shared library caches.
