Mitigation Strategies

Immediately update the `clean()` function in `searchresults.php` to use `htmlspecialchars()` for encoding dynamic values before outputting them in HTML context. This prevents malicious script execution. Additionally, restrict user input validation and consider implementing a web application firewall as a temporary measure.
