What are the potential pitfalls of using a Template-Engine in PHP?

One potential pitfall of using a Template-Engine in PHP is the risk of introducing security vulnerabilities if user input is not properly sanitized. To mitigate this risk, always ensure that user input is sanitized before being passed to the template engine to prevent cross-site scripting attacks. 

// Example of sanitizing user input before passing it to a template engine
$userInput = $_POST['user_input'];
$sanitizedInput = htmlspecialchars($userInput, ENT_QUOTES, 'UTF-8');
$template->assign('user_input', $sanitizedInput);
