## Description

The URL Shortify – Simple and Easy URL Shortener plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via query parameters on the bundled Freemius SDK pricing admin page in all versions up to, and including, 2.7.1. This is due to the pricing template merging raw $_GET values over trusted configuration keys (such as contact_url, request_handler_url, fs_wp_endpoint_url and selector) before passing them to the pricing JavaScript application, which uses contact_url unvalidated as a link href. This makes it possible for unauthenticated attackers to inject arbitrary web scripts (for example through a javascript: contact URL) or point the pricing app's requests at an attacker-controlled endpoint. The attacker has to trick an administrator into opening a crafted link and interacting with the page.
