What are some potential pitfalls when using IFrames in PHP for dynamically loading content?

One potential pitfall when using IFrames in PHP for dynamically loading content is the risk of exposing sensitive information or being vulnerable to cross-site scripting attacks if the content being loaded is not properly sanitized. To mitigate this risk, it is important to validate and sanitize any user input before including it in the IFrame source. 

// Sanitize user input before including it in the IFrame source
$iframeSrc = filter_var($_GET['src'], FILTER_SANITIZE_URL);

// Output the IFrame with the sanitized source
echo '<iframe src="' . $iframeSrc . '"></iframe>';
