To detect this reflected XSS vulnerability in WP Customer Area, inspect web traffic for malicious scripts in URLs or form inputs. Check for unusual GET/POST parameters containing JavaScript code. Use browser developer tools to monitor network requests for suspicious payloads like <script> tags or event handlers (e.g., onmouseover).

Scan web server logs for requests with XSS payloads (e.g., %3Cscript%3E). Tools like OWASP ZAP or Burp Suite can automate detection by fuzzing inputs with XSS test strings.
