A sandbox bypass vulnerability involving various casts performed implicitly by the Groovy language runtime in Jenkins Pipeline: Groovy Plugin 2802.v5ea_628154b_c2 and earlier allows 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.
A sandbox bypass vulnerability exists in Jenkins Groovy Plugin in src/main/java/hudson/plugins/groovy/StringScriptSource.java allowing attackers with Overall/Read permission to execute arbitrary code on the Jenkins master JVM.
