What is CVE-2017-16653?

A flaw in the CSRF protection mechanism was identified in Symfony versions prior to specified updates. The vulnerability arises from the identical usage of tokens for both HTTP and HTTPS requests. This opens a potential window for man-in-the-middle (MITM) attacks on HTTP connections, where an attacker could intercept the token and leverage it for CSRF attacks when the target application is accessed securely over HTTPS.
