Vulnerability Title
HUSKY <= 1.4.3 - Reflected Cross-Site Scripting
Source: CVE Program / CVE List V5
Vulnerability Description
The HUSKY – Products Filter Professional for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via SEO-friendly permalink filter URL segments in versions up to, and including, 1.4.3. This is due to insufficient input sanitization and output escaping in the wp_load_js() function, which reads filter values from the URL path via the url_request extension's parse_url_query() and embeds them into an inline JavaScript string using json_encode() without escaping single quotes. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link.
