What potential security risks are involved in redirecting users to a different PHP file based on their status?

When redirecting users to a different PHP file based on their status, potential security risks include exposing sensitive information, allowing unauthorized access to restricted files, and potential for injection attacks. To mitigate these risks, it is important to validate user status and permissions before redirecting them to a different PHP file to ensure they have the necessary access rights.

// Validate user status before redirecting
if($user_status == 'admin'){
    header('Location: admin.php');
    exit();
} elseif($user_status == 'user'){
    header('Location: user.php');
    exit();
} else {
    // Handle unauthorized access or redirect to a default page
    header('Location: default.php');
    exit();
}
