## Description

The WPC Smart Quick View for WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.4.1. The 'woosq_quickview' WooCommerce AJAX endpoint renders a product's summary without checking whether the product is password-protected. This makes it possible for unauthenticated attackers to read the short description of password-protected products, and the full description where the quick view is configured to show it. WooCommerce otherwise shows this content only after the product password is entered.
