## Description

The Product Category Slider & Grid for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery via the 'sp-wcsp-woo' query parameter in all versions up to, and including, 1.7.2, due to missing nonce validation in the admin_notice() function. This makes it possible for unauthenticated attackers to install and activate the WooCommerce plugin by tricking a site administrator into clicking a link.
