## Description

The reactpress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'permalink' parameter of the repr_admin_ajax_request AJAX action in all versions up to, and including, 3.4.0, due to a missing capability check and insufficient sanitization of the HTML downloaded from the supplied URL before it is written to an app's index.html file. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts into an app's index.html file served from the site, which will execute whenever a user accesses that file.
