What fixes it

  • 2.7.8Asaas Gateway for WooCommerceCVE List

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

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.
