CVE-2026-92125Network attack vector

Controller code execution via unblocked AST transformations

Published Sep 16, 2026 · Updated Sep 16, 2026

Sandbox bypass in Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier allows remote authenticated users to execute code. The sandbox compiler fails to reject @GroovyASTTransformationClass, so a submitted script can load and run an arbitrary AST transformation before sandbox enforcement. Exploitation requires permission to define and run sandboxed scripts, including Pipelines, and executes code in the Jenkins controller JVM.
