Boom Fest <= 2.2.1 - Missing Authorization to Authenticated (Subscriber+) Plugin Settings Update

The Boom Fest plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'bf_admin_action' function in all versions up to, and including, 2.2.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update plugin settings that change the appearance of the website.
