## Description

The HUSKY – Products Filter for WooCommerce Professional plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the settings import feature in all versions up to, and including, 1.4.6. This is due to the 'woof_do_import_data' AJAX handler only applying wc_clean() to imported settings, which leaves JavaScript without HTML tags intact, and not stopping users without the unfiltered_html capability from setting the 'js_after_ajax_done' value, which is printed unescaped inside an inline script on front-end pages that use the filter. This makes it possible for authenticated attackers with Shop Manager-level access and above to inject arbitrary web scripts that execute whenever a user accesses an injected page.
