Vulnerability Title
Rede Itaú for WooCommerce — Payment PIX, Credit Card and Debit <= 5.1.2 - Unauthenticated Order Status Manipulation
Source: CVE Program / CVE List V5
Vulnerability 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.
