What are the potential pitfalls of using $_GET without specifying parameter names?

Using $_GET without specifying parameter names can lead to security vulnerabilities such as SQL injection attacks or unintended data exposure. To mitigate these risks, it is important to always validate and sanitize user input before using it in your application. 

// Example of how to specify parameter names when using $_GET
if(isset($_GET['id'])){
    $id = filter_var($_GET['id'], FILTER_SANITIZE_NUMBER_INT);
    // Use $id in your application
}
