Pay With MetaMask For WooCommerce – Cryptocurrency Payment Gateway <= 1.7.2 - Unauthenticated Arbitrary Order Payment Bypass
The Pay With MetaMask For WooCommerce – Cryptocurrency Payment Gateway plugin for WordPress is vulnerable to Bypass Vulnerability in all versions up to, and including, 1.7.2. This is due to the transaction verification function accepted a caller-supplied amount and read the receiver address from global plugin settings rather than from trusted order metadata, allowing the expected payment parameters to be manipulated by the client. This makes it possible for unauthenticated attackers to mark WooCommerce orders as paid without completing a valid on-chain payment matching the order's expected receiver, amount, and token contract.
