What it is

The PDF Builder for WooCommerce. Create invoices,packing slips and more plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.0.11. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve invoice numbers, formatted invoice numbers, and creation timestamps for arbitrary WooCommerce orders by supplying any OrderNumber and InvoiceId values with a garbage nonce.
