What is CVE-2026-92123?

The Jenkins Script Security Plugin versions 1415.v9a_f9b_3a_c253d and earlier have a significant flaw that fails to intercept operations on a null receiver. This deficiency enables authorized users to run sandboxed scripts, including Pipelines, thereby circumventing the intended sandbox protections. As a result, attackers can exploit this vulnerability to execute arbitrary code within the Jenkins controller's JVM, posing a serious risk to affected systems.
