CVE-2026-92131: Jenkins Project Jenkins Pipeline: Groovy Libraries Plugin

Medium severity, CVSS 4.2. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
