CVE-2026-87974 Details
Description
The Asaas Gateway for WooCommerce WordPress plugin before 2.7.8 does not properly authenticate its payment webhook, accepting an empty access token in its default configuration and not verifying that the confirmed payment corresponds to the order it marks paid, allowing unauthenticated attackers to mark arbitrary orders as paid.
A vulnerability exists in the Asaas Gateway for WooCommerce WordPress plugin in versions prior to 2.7.8. The issue arises because the plugin's payment webhook does not properly authenticate requests. It accepts an empty access token by default and fails to verify that confirmed payments correspond to the orders being marked as paid. This allows unauthenticated attackers to manipulate order statuses and mark arbitrary orders as paid.
Users are advised to update the Asaas Gateway for WooCommerce WordPress plugin to version 2.7.8 or later.
