What are some potential pitfalls of using pre-built forum scripts for PHP websites?

One potential pitfall of using pre-built forum scripts for PHP websites is security vulnerabilities. These scripts may not always be up-to-date with the latest security patches, leaving your website susceptible to attacks. To mitigate this risk, it is important to regularly update the forum script and implement additional security measures such as input validation and user authentication. 

// Example of implementing input validation in a PHP forum script
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $post_content = htmlspecialchars($_POST["post_content"]);
    // Additional validation and sanitization steps can be added here
}
