## Description

The Social Slider Feed plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 2.3.8 due to a missing capability check on the admin page controller dispatch (the fy_page/fy_plugin/fy_action/fy_ajax parameters and the page action executor, which run on the admin_menu hook before WordPress checks page access) and on the GET 'action'/'social' handling of the feeds and profiles pages. This makes it possible for authenticated attackers, with Subscriber-level access and above, to render the plugin's admin pages, including the nonces they contain, and to add, edit or delete feeds and delete connected social profiles.
