Summary
A cross-site request forgery (CSRF) vulnerability in Jenkins Pipeline: Groovy Libraries Plugin 798.v5cc688825312 and earlier allows attackers to delete shared library caches.
Risk Assessment
An attacker can force a logged-in user to perform an unwanted action of deleting the cache, which may disrupt pipeline operations and increase system load.
Recommendation
Update the Pipeline: Groovy Libraries plugin to a version that fixes the CSRF vulnerability. Additionally, consider enabling CSRF protection in Jenkins and restricting access to administrative functions.
Other vulnerabilities in Jenkins Pipeline: Groovy Libraries Plugin
See all- CVE-2026-92131Medium
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.
- CVE-2026-48921High
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.
