Doc Text:
A flaw was found in the Jenkins Script Security Plugin. Attackers with permissions to define and run sandboxed scripts, including Pipelines, can exploit this vulnerability. The plugin does not properly intercept operations performed on a null receiver, such as method calls or property accesses. This oversight allows an attacker to bypass the sandbox protection and execute arbitrary code within the Jenkins controller's Java Virtual Machine (JVM).

Description OSIDB Bzimport 2026-09-16 14:19:32 UTC
Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier does not intercept operations performed on a null receiver (method calls, property and attribute accesses, and array accesses), allowing attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.
