What potential security risks can arise from not verifying the user group in a PHP login script?

Not verifying the user group in a PHP login script can lead to unauthorized access to certain parts of the application or sensitive information. To solve this issue, it is important to verify the user group during the login process and restrict access based on the user's group. 

// Verify user group during login process
if ($user_group !== 'admin') {
    // Redirect user to unauthorized page or display an error message
    header("Location: unauthorized.php");
    exit();
}

// Rest of the login script
