## Description

The HUSKY – Products Filter for WooCommerce Professional plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'JavaScript code after AJAX is done' (js_after_ajax_done) setting in all versions up to, and including, 1.4.2. This is due to the settings save routine requiring only the manage_woocommerce capability, not unfiltered_html, before storing JavaScript that is printed unescaped into the front-end inline script. This makes it possible for authenticated attackers with Shop Manager-level access and above, who lack the unfiltered_html capability, to inject arbitrary web scripts that execute in the browsers of visitors using the product filter.
