The Appointment Booking Calendar — Simply Schedule Appointments plugin for WordPress is vulnerable to unauthorized access of sensitive data in all versions up to and including 1.6.9.29. This is due to two compounding weaknesses: (1) a non-user-bound is exposed to unauthenticated users through the public REST endpoint, and (2) the method in relies on for authorization (which accepts the public nonce) but does not call to filter restricted fields. This makes it possible for unauthenticated attackers to access admin-only plugin settings including the administrator email, phone number, internal access tokens, notification configurations, and developer settings via the endpoint. The exposure of appointment tokens also allows an attacker to modify or cancel appointments.
