Jenkins Script Security Plugin lets attackers run code

CVE-2026-92125 · published 1 month ago
Summary

The Script Security Plugin for Jenkins does not block a special annotation that lets users change how scripts are compiled. An attacker who can add or edit sandboxed scripts, such as build pipelines, could use this to run any code on the Jenkins server. Update the plugin to the latest version or restrict script‑editing permissions to stop this risk.

Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d 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.
