Until an official fix is available, users should monitor for vendor updates and consider implementing additional verification controls on payment callbacks if possible.
Description
The Rede Itaú for WooCommerce plugin for WordPress is vulnerable to order status manipulation due to insufficient verification of data authenticity in all versions up to, and including, 5.1.2. This is due to the plugin failing to verify the authenticity of payment callbacks. This makes it possible for unauthenticated attackers to manipulate WooCommerce order statuses, either marking unpaid orders as paid, or failed.
