 "title": "Faktur Pro for WooCommerce <= 3.2.2 - Authenticated (Customer+) Insecure Direct Object Reference to Customer Invoice Download via 'order' Parameter",
 "description": "The Faktur Pro for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'order' parameter of the fakturpro_customer_invoice AJAX action in all versions up to, and including, 3.2.2, due to the handler checking only a generic, non-order-specific nonce and not validating that the requested order belongs to the current user. This makes it possible for authenticated attackers, with customer-level access and above, to download the invoice PDFs of other customers' orders, exposing their names, addresses and order details.",
