Upgrade org.jenkins-ci.plugins:script-security to version 1402.v94c9ce464861 or higher.
Overview
org.jenkins-ci.plugins:script-security is a package that allows Jenkins administrators to control what in-process scripts can be run by less-privileged users.
Affected versions of this package are vulnerable to Use of Password Hash Instead of Password for Authentication through the getClasspathRenderInfo method in ScriptApproval. An attacker can retrieve pending classpath entry details by sending an Ajax request to this @JavaScriptMethod without administrator privileges. This exposes the hashes and filesystem paths of pending classpath entries to users who only have read access, leaking local path information from the Jenkins controller.
Notes
- The exposed data includes both pending and approved Script Security classpaths, so the leak is not limited to entries awaiting review; it can also enumerate classpath details that have already been approved.
