WebToffee WooCommerce PDF Invoices, Packing Slips, Delivery Notes & Shipping Labels <= 5.0.2 - Insecure Direct Object Reference to Unauthenticated Unauthorized Order Document Access via 'email' Parameter
The WebToffee WooCommerce PDF Invoices, Packing Slips, Delivery Notes & Shipping Labels plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) in versions up to, and including, 5.0.2.
The vulnerability exists in the guest print_document_from_the_mail_link handler dispatched from print_window() on the init action hook. The handler authorizes access to printable order documents when the user-supplied (base64-encoded) email parameter matches the order's billing email—a non-secret identifier—rather than requiring the secret WooCommerce order_key.
When the site allows guest document access (configured such that 'wt_pklist_print_button_access_for' != 'logged_in'), unauthenticated attackers who know a target order ID and its corresponding billing email can access customer documents. Exposed documents may include invoices, packing slips, delivery notes, and shipping labels containing sensitive details such as customer names, billing and shipping addresses, phone numbers, purchased products, prices, taxes, and invoice metadata.
What to do
Update the print-invoices-packing-slip-labels-for-woocommerce plugin to version 5.0.3 or later.
