CVE-2026-18562

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.
