Youzify – BuddyPress Community, User Profile, Social Network & Membership Plugin for WordPress <= 1.3.3 - Missing Authorization to Authenticated (Subscriber+) Limited Options Update (save_addon_key_license)

The Youzify – BuddyPress Community, User Profile, Social Network & Membership Plugin for WordPress plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the save_addon_key_license() function in all versions up to, and including, 1.3.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary options to a value of a valid license key.
