Summary
The WP BASE Booking of Appointments, Services and Events WordPress plugin lets an authenticated user with Subscriber-level access create a new administrator account, which gives them full administrative control of the site. The flaw is reached by logging in with any Subscriber-level account, since one of the plugin's user-creation actions does not restrict access properly.
