What are the potential pitfalls of passing sessions via URL parameters in PHP for server-to-server communication?

Passing sessions via URL parameters in PHP for server-to-server communication can potentially expose sensitive session data in the URL, making it vulnerable to interception or unauthorized access. To mitigate this risk, it is recommended to use secure methods of communication such as HTTPS and encrypt sensitive data before passing it in the URL. 

// Encrypt session data before passing it in the URL
$encryptedSessionData = base64_encode(openssl_encrypt(serialize($_SESSION), 'AES-256-CBC', 'your_secret_key', 0, 'your_iv'));

// Pass encrypted session data in the URL
$url = "https://example.com/api?session=" . $encryptedSessionData;
