The Team – Team Members Showcase Plugin plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the response() function in all versions up to, and including, 4.4.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the plugin's settings.
