Controller code execution via unintercepted implicit casts
Published Oct 19, 2022 · Updated Aug 3, 2024
Sandbox bypass in Jenkins Pipeline: Groovy 2802.v5ea_628154b_c2 and earlier allows remote authenticated users to execute controller code. The Groovy runtime performs implicit casts in method returns, assignments, and default arguments without the sandbox intercepting and allowlisting those operations. The attacker must already have permission to define and run sandboxed scripts; successful exploitation executes arbitrary code in the Jenkins controller JVM.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
