CVE-2026-92124: Jenkins Script Security Plugin vulnerability
Jenkins Script Security Plugin 1415.v9af9b3ac253d and earlier checks the operations Groovy will perform with the elements it reads from a collection that a sandboxed script casts to another type but performs the cast on the collection itself, 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.
