Authenticated code execution via unchecked dynamic methods
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 omits security checks when a sandboxed script calls methods added dynamically to a class at runtime. Permission to define and run sandboxed scripts, including Pipelines, is required, and successful exploitation runs code outside the sandbox on the Jenkins controller.
