## Description

The reactpress plugin for WordPress is vulnerable to unauthorized modification and loss of data via the repr_admin_ajax_request AJAX action in all versions up to, and including, 3.4.0, due to a missing capability check and missing nonce verification in the repr_handle_admin_ajax_request() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete the directories and settings of ReactPress apps, create published pages, assign apps to pages, detach apps from pages and toggle client-side routing.
