Link to public exploit:

Vulnerability description

The vulnerability allows a remote attacker to bypass sandbox restrictions.

The vulnerability exists due to improper access restrictions in "pipeline-model-definition/src/main/groovy/org/jenkinsci/plugins/pipeline/modeldefinition/parser/Converter.groovy" when applying AST transforming annotations such as @Grab to source code elements. A remote authenticated attacker with Overall/Read permission, or able to control Jenkins file or sandboxed Pipeline shared library contents in SCM, can provide a pipeline script to an HTTP endpoint and execute arbitrary code on the Jenkins master JVM.
