Check if Vulnerable:
Test by injecting a simple XSS payload like <script>alert('test')</script> into the search parameter and check if it executesCheck Version:
Check the software version in the admin panel or readme filesVerify Fix Applied:
After implementing fixes, test with the same XSS payloads to ensure they are properly sanitized and don't execute📡 Detection & Monitoring
