Advisory

Source description from Wordfence Intelligence, credited to Naoki Kawahigashi.

The CryptoCloud – Crypto Payment Gateway plugin for WordPress is vulnerable to Missing Authentication in versions 3.0.0 through 3.0.1. This is due to a skipped integrity check on incoming payment gateway webhook notifications combined with a webhook secret that defaults to an empty value, meaning no signature validation is ever enforced. This makes it possible for unauthenticated attackers to mark arbitrary WooCommerce orders as paid or failed without completing any actual payment transaction.
