What are the potential risks or security concerns when passing post variables without a form?

When passing post variables without a form, there is a risk of exposing sensitive data or allowing unauthorized access to your application. To mitigate this risk, you should always validate and sanitize the input data before using it in your application. Additionally, you can implement server-side validation to ensure that only authorized users can access the data. 

<?php
// Validate and sanitize input data
if(isset($_POST['variable'])){
    $variable = $_POST['variable'];
    // Sanitize the input data
    $sanitized_variable = filter_var($variable, FILTER_SANITIZE_STRING);
    
    // Perform server-side validation
    if(/* Add your validation logic here */){
        // Process the data
    } else {
        // Handle unauthorized access
        die("Unauthorized access");
    }
}
?>
