What is CVE-2020-2110?

The Jenkins Script Security Plugin prior to version 1.70 is vulnerable to sandbox protection circumvention. Attackers can exploit this flaw during the script compilation phase by leveraging AST (Abstract Syntax Tree) transforming annotations on imports or embedding these annotations within others. This undermines the security model expected in Jenkins, allowing potentially harmful scripts to bypass protective barriers, putting systems at risk.

Affected Version(s)

Jenkins Script Security Plugin <= 1.69
