Until a fix is available, it is recommended to restrict access to the WooCommerce Store API endpoints if possible and monitor for suspicious activity related to invoice generation. Avoid using affected plugin versions in production environments.
Description
The PDF Invoice for WooCommerce + Drag and Drop Template Builder WordPress plugin versions up to 7.1.1 is vulnerable to PHP Object Injection via the 'customer_note' parameter. This vulnerability arises from insufficient sanitization of user input, allowing unauthenticated attackers to execute arbitrary code on the server by exploiting the invoice generation process triggered during checkout.
