Product Configurator for WooCommerce < 1.7.3 - Unauthenticated Private/Draft Product Data Disclosure via pc_get_data

The Product Configurator for WooCommerce WordPress plugin before 1.7.3 does not perform any authorisation or post-status check before returning WooCommerce product data through a public AJAX action, allowing unauthenticated users to retrieve the data (title, price, weight, stock status, and configurator option pricing/SKUs) of private and draft, non-public products by supplying the product ID. WordPress post-visibility controls are bypassed.
