Both the pipeline validation REST APIs and actual script/pipeline execution are affected. This allowed users with Overall/Read permission, or able to control Jenkinsfile or sandboxed Pipeline shared library contents in SCM, to bypass the sandbox protection and execute arbitrary code on the Jenkins master. All known unsafe AST transformations in Groovy are now prohibited in sandboxed scripts. Severity o SECURITY-1266: High Affected Versions o Pipeline: Declarative Plugin up to and including 1.3.4 o Pipeline: Groovy Plugin up to and including 2.61 o Script Security Plugin up to and including 1.49 Fix o Pipeline: Declarative Plugin should be updated to version 1.3.4.1 o Pipeline: Groovy Plugin should be updated to version 2.61.1 o Script Security Plugin should be updated to version 1.50 These versions include fixes to the vulnerabilities described above. All prior versions are considered to be affected by these vulnerabilities unless otherwise indicated.
