Summary
The CCAvenue Payment Gateway for WooCommerce WordPress plugin through 3.1 does not verify that payment-confirmation requests come from the payment provider (CWE-284). Its verification key is empty on a default install, so an unauthenticated remote attacker can forge a confirmation and mark any WooCommerce order as paid without payment. An exploit link is listed in the references.

Description from the CNA
The CCAvenue Payment Gateway for WooCommerce WordPress plugin through 3.1 does not verify that a payment-confirmation request genuinely originates from the payment provider, and derives its verification key from a value that is empty on a default install, allowing unauthenticated attackers to forge a confirmation and mark any WooCommerce order as paid without payment.
