What are the potential pitfalls of implementing a system that evaluates and distributes superglobal variable data to different classes or objects in PHP?

One potential pitfall of implementing a system that evaluates and distributes superglobal variable data to different classes or objects in PHP is the risk of exposing sensitive information or creating security vulnerabilities. To mitigate this risk, it is important to validate and sanitize the input data before passing it to classes or objects to prevent injection attacks or unauthorized access. 

// Example of validating and sanitizing input data before passing to classes or objects
$input_data = $_POST['user_input']; // Assuming 'user_input' is a superglobal variable
$clean_input = filter_var($input_data, FILTER_SANITIZE_STRING);

// Pass the sanitized input data to a class or object
$object = new MyClass($clean_input);
