## Description

The Hippoo Mobile App for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'token_id' parameter of a REST API endpoint that renders a login redirect page in all versions up to, and including, 1.12.0 due to insufficient input sanitization and output escaping when the value is placed into an inline JavaScript string and the page HTML. 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 link.
