What is CVE-2026-78172?

The Themify – WooCommerce Product Filter plugin for WordPress is susceptible to Reflected Cross-Site Scripting due to inadequate input sanitization and improper output escaping methods. This vulnerability allows unauthenticated attackers to inject arbitrary web scripts into web pages through query parameters. If a user is manipulated into clicking on a malicious link, the injected scripts are executed within their browser session, potentially leading to unauthorized actions or data exposure. It is crucial for users of the plugin to upgrade to the latest version to mitigate this risk.
