Vulnerability description
The vulnerability allows a remote attacker to bypass sandbox restrictions.
The vulnerability exists due to improper access restrictions in "src/main/java/org/jenkinsci/plugins/scriptsecurity/sandbox/groovy/GroovySandbox.java" 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 bypass the sandbox protection and execute arbitrary code on the Jenkins master.
