## Description

The WOW Styler for CF7 – Visual Styler for Contact Form 7 Forms plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via query-string parameters on the pricing admin page of the bundled Freemius SDK in all versions up to, and including, 1.8.5. This is due to $_GET values being merged after the trusted configuration values passed to the Freemius pricing JavaScript app, so request parameters such as contact_url, fs_wp_endpoint_url and request_handler_url override them without validation. The contact_url value is rendered as the href of the pricing page's contact links. This makes it possible for unauthenticated attackers to inject arbitrary web scripts (for example through a javascript: URL) or to point the pricing app's requests and redirects at attacker-controlled URLs. The attacker must trick a logged-in administrator into opening a crafted link and interacting with the page.
