## Description

The Product Category Slider & Grid for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via slider settings such as the section title, shop now button text, link target, product count before/after text, and slider configuration values in all versions up to, and including, 1.7.2 due to insufficient output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
