What are the potential pitfalls of using sessions to control script execution in PHP?

One potential pitfall of using sessions to control script execution in PHP is that it can lead to security vulnerabilities if not properly handled. To mitigate this risk, developers should ensure that session data is properly sanitized and validated before using it to control script execution. 

<?php
session_start();

// Validate session data before using it
if(isset($_SESSION['authenticated']) && $_SESSION['authenticated'] === true) {
    // Proceed with script execution
} else {
    // Redirect or display an error message
}
?>
