CVE-2026-93746 Details
Description
The WebToffee WooCommerce PDF Invoices, Packing Slips, Delivery Notes & Shipping Labels plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 5.0.2 via the 'email' parameter of the guest print_document_from_the_mail_link handler dispatched from print_window() on init. This is due to the handler authorizing access to an order's printable documents when the attacker-supplied (base64-encoded) 'email' equals the order's billing email — a non-secret identifier — instead of requiring the WooCommerce order_key. This makes it possible for unauthenticated attackers, when the site is configured to allow guest access to documents ('wt_pklist_print_button_access_for' != 'logged_in'), to retrieve any other customer's invoice, packing slip, delivery note, dispatch label or shipping label — including customer name, billing/shipping address, phone number, purchased products, prices, taxes and invoice metadata — by knowing the target order ID and the associated billing email address.
A vulnerability allowing Insecure Direct Object Reference has been identified in the WebToffee WooCommerce PDF Invoices, Packing Slips, Delivery Notes & Shipping Labels plugin for WordPress, affecting versions through 5.0.2. The vulnerability arises in the 'email' parameter of the guest print_document_from_the_mail_link handler, which is triggered during the initialization phase. The issue occurs because the handler improperly authorizes access to an order's printable documents based on the billing email — a non-secret identifier — instead of the WooCommerce order_key. This flaw enables unauthenticated attackers to access any customer's invoice or shipping document, including sensitive information such as names, addresses, phone numbers, purchased products, and invoice metadata, by knowing the target order ID and billing email, particularly when the site allows guest access to documents.
Users are advised to update the plugin to version 5.0.3 or a newer patched version.
