Description
The PDF Invoice for WooCommerce + Drag and Drop Template Builder plugin for WordPress contains a critical PHP Object Injection vulnerability in all versions up to and including 7.1.1. This flaw arises from insufficient sanitization of the 'customer_note' checkout field, allowing unauthenticated attackers to execute arbitrary code on the server by exploiting the invoice generation process triggered during checkout.
