Check if Vulnerable:
Check if /admin/registration.php exists and contains unsanitized uname parameter handlingCheck Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test the registration.php endpoint with SQL injection payloads to confirm they're blocked📡 Detection & Monitoring
Log Indicators:
