Are there any security concerns to consider when passing data between frames in PHP?

When passing data between frames in PHP, security concerns may arise if the data being passed is not properly sanitized or validated. To ensure data integrity and prevent any potential security vulnerabilities, it is important to sanitize and validate the data before passing it between frames. This can be done by using PHP functions like htmlspecialchars() to escape special characters and prevent XSS attacks. 

// Sanitize and validate data before passing between frames
$data = $_POST['data'] ?? ''; // Retrieve data from POST request
$clean_data = htmlspecialchars($data); // Sanitize data to prevent XSS attacks
// Pass $clean_data between frames
