Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Jenkins Script Security Plugin 1402.v94c9ce464861 and earlier does not reject Groovy AST transformation annotations carrying an extensions member, allowing attackers able to run sandboxed Groovy scripts to execute code outside the sandbox if a suitable script is present on the classpath of the component that evaluates the script.
