## Description

The Joli Table Of Contents plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL query parameters on the bundled Freemius pricing page in all versions up to, and including, 3.0.3. This is due to user-supplied $_GET values being merged over the trusted configuration values passed to the pricing JavaScript application, such as contact_url, request_handler_url and fs_wp_endpoint_url, without validation. This makes it possible for unauthenticated attackers to inject arbitrary web scripts, for example as a javascript: URL in the pricing page's contact links, that execute if they can trick an administrator into opening a crafted link and interacting with the page.
