CVE-2026-92125: Jenkins Script Security Plugin vulnerability
Jenkins Script Security Plugin 1415.v9af9b3ac253d and earlier does not reject the @GroovyASTTransformationClass annotation, allowing attackers with permission to define and run sandboxed scripts, including Pipelines, to run an arbitrary AST transformation at compile time, bypassing the sandbox protection and executing arbitrary code in the context of the Jenkins controller JVM.

Frequently Asked Questions
Who can exploit this issue?
An attacker must have permission to define and run sandboxed scripts, including Jenkins Pipelines. The issue allows that attacker to bypass sandbox protection and execute arbitrary code in the Jenkins controller JVM context.
Are sandboxed Pipelines affected?
Yes. Sandboxed scripts, including Pipelines, are explicitly affected because the annotation can cause an arbitrary AST transformation to run at compile time.
How can I determine whether my Jenkins instance is affected?
Check the installed Jenkins Script Security Plugin version. Versions 1415.v9a_f9b_3a_c253d and earlier are affected.
