Check if Vulnerable:
Test /pet1/update_cnp.php with SQL injection payloads like ' OR '1'='1 in ID parameterCheck Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Verify input validation rejects non-numeric ID values and SQL injection attempts return error pages📡 Detection & Monitoring
