What potential pitfalls should be considered when using PHP to define video files for automatic embedding?

One potential pitfall when using PHP to define video files for automatic embedding is the risk of exposing sensitive file paths or information to users. To mitigate this risk, it is important to sanitize user input and validate file paths before using them in the code. 

// Sanitize user input and validate file paths before embedding video files
$video_path = filter_var($_POST['video_path'], FILTER_SANITIZE_STRING);

if (file_exists($video_path)) {
    echo '<video controls>';
    echo '<source src="' . $video_path . '" type="video/mp4">';
    echo '</video>';
} else {
    echo 'Invalid video file path';
}
