The PiWeb Cancel order / Refund request for WooCommerce WordPress plugin before 1.3.4.34 does not have authorization or ownership checks when adding the contents of a previous order to the cart, allowing unauthenticated users to disclose the contents of other customers' orders, as well as to clear and repopulate a logged in user's cart via a crafted link.
