What are some potential security risks associated with allowing users to shut down local PCs through a web application?

Allowing users to shut down local PCs through a web application can pose security risks such as unauthorized access, potential misuse by malicious users, and system instability if not properly implemented. To mitigate these risks, it is important to implement proper authentication and authorization checks before allowing users to initiate a shutdown command. 

<?php
session_start();

if($_SESSION['authenticated'] === true && $_SESSION['role'] === 'admin') {
    exec('shutdown -s -t 0');
    echo 'Shutdown command has been initiated.';
} else {
    echo 'Unauthorized access.';
}
?>
