Doc Text:
A flaw was found in the Jenkins Script Security Plugin. Attackers with permissions to define and run sandboxed scripts, such as Pipelines, can exploit this vulnerability. By not properly rejecting the @GroovyASTTransformationClass annotation, an attacker can run an arbitrary Abstract Syntax Tree (AST) transformation at compile time. This bypasses the sandbox protection, leading to arbitrary code execution within the Jenkins controller Java Virtual Machine (JVM).

Description OSIDB Bzimport 2026-09-16 14:14:24 UTC
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.
