Upstream source description

The TrueBooker WordPress plugin before 1.3.0 does not perform any capability check on one of its setup handlers, and the token it does check is issued to unauthenticated visitors, allowing anyone to overwrite the plugin's entire configuration and to discard any setting they do not supply.
