Summary

The Return Refund and Exchange For WooCommerce WordPress plugin before version 4.6.4 does not correctly verify the ownership of guest orders in some of the AJAX actions it exposes to unauthenticated users. This allows them to read private order messages, post messages and attachments in the customer's name, and cancel return requests on any guest order.

Risk Assessment

The risk includes customer privacy breaches, impersonation of customers, and manipulation of the return process. Attackers could also disrupt store operations or cause financial damage.

Recommendation

Update the Return Refund and Exchange For WooCommerce plugin to version 4.6.4 or later. Also review AJAX logs and verify access permissions for guest orders.
