CVE-2025-31722Network attack vector

Authenticated code execution via unsandboxed folder libraries

Published Apr 2, 2025 · Updated Feb 26, 2026

Code injection in Jenkins Templating Engine Plugin 2.5.3 and earlier allows remote authenticated users to execute code in the controller JVM. StepWrapperFactory compiles every library step with exec.getTrustedShell(), so folder-scoped Groovy supplied by Item/Configure users bypasses Script Security. Item/Configure permission on a folder is required; successful exploitation runs arbitrary code with the Jenkins controller's privileges.
