Root Cause Analysis
The vulnerability stems from the ActiveDirectoryStatus class handling the domain health check endpoint without proper authorization. In versions ≤2.19, the class did not implement StaplerProxy or override getRequiredPermission(), allowing access with Overall/Read permissions. The fix in 2.20 added getTarget() (to enforce permission checks via checkPermission()) and getRequiredPermission() (to require ADMINISTER), which were missing in vulnerable versions. The class itself acts as the entry point for the insecure endpoint, making it the core vulnerable component.
