Jenkins Splunk Plugin Sandbox Bypass
Jenkins Splunk Plugin has a form validation HTTP endpoint used to validate a user-submitted Groovy script through compilation, which was not subject to sandbox protection. This allowed attackers with Overall/Read access to execute arbitrary code on the Jenkins controller by applying AST transforming annotations such as @Grab to source code elements.
The affected HTTP endpoint now applies a safe Groovy compiler configuration preventing the use of unsafe AST transforming annotations.
