CVE-2026-92131
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.
