Check if Vulnerable:
Test if unauthorized users can modify group_id parameter in requests to /admin/operation/user.php and perform administrative actionsCheck Version:
Check software version in admin panel or application configuration filesVerify Fix Applied:
Verify that proper authorization checks are implemented and unauthorized group_id manipulation no longer works📡 Detection & Monitoring
Log Indicators:
