Description
The reactpress plugin for WordPress is vulnerable to Server-Side Request Forgery via the 'permalink' parameter of the repr_admin_ajax_request AJAX action in all versions up to, and including, 3.4.0. The repr_handle_admin_ajax_request() function has no capability check, and the index.html generation routine fetches any supplied URL with wp_remote_get() and writes the response into the app directory. This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations from the web application, which can be used to query and modify information from internal services.
