Description

The Woo PDF Invoice Builder plugin (also distributed as "PDF Builder for WooCommerce") for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.0.8. This is due to the InspectOrder() AJAX handler (woocommerce-pdf-invoice-ajax.php:513), registered on wp_ajax_rednao_wcpdfinv_inspect_order, performing no capability check and no nonce verification before loading an arbitrary order by the attacker-supplied 'OrderNumber' POST field and serializing its full WC_Order::get_data() and meta to the response. This makes it possible for authenticated attackers with Subscriber-level access and above to read every WooCommerce order on the site — including billing/shipping address, email, phone number, payment method, gateway transaction ID, and order totals — by iterating order IDs.
