Are there any potential security risks associated with passing variables from a shell script to a PHP script?

Passing variables from a shell script to a PHP script can pose security risks if the input is not properly sanitized. To mitigate these risks, it is crucial to validate and sanitize the input data before using it in the PHP script. This can help prevent common vulnerabilities such as SQL injection, cross-site scripting, and command injection. 

<?php
// Sanitize input data from shell script
$variable = filter_input(INPUT_GET, 'variable', FILTER_SANITIZE_STRING);

// Use the sanitized variable in your PHP script
echo "The variable passed from the shell script is: " . $variable;
?>
