The Salon Booking System WordPress plugin through version 10.30.33 does not perform any capability check or validate an OAuth state value on its Google Calendar authorization callback, which is also hooked for unauthenticated users. This allows an unauthenticated attacker to overwrite the site's stored Google Calendar connection tokens with attacker-controlled ones and hijack the integration. Exploitation requires the site to have configured its own Google OAuth client for the calendar feature.

The Salon Booking System WordPress plugin before version 10.30.34 does not properly validate a booking's ownership token before loading it in its booking-wizard confirmation steps. This allows unauthenticated attackers to disclose other customers' booking records, including personal information, by supplying a sequential booking identifier.

The Salon Booking System WordPress plugin through 10.31.0 does not verify that a requested booking belongs to the caller on one of its REST API endpoints, requiring only a basic read capability, allowing any authenticated user (including a Subscriber or self-registered customer account) to disclose any customer's booking personal data such as name, email, phone number, address and private notes by enumerating booking identifiers.

The Salon Booking System WordPress plugin before version 10.30.20 lacks proper authorization checks on one of its AJAX actions, allowing any authenticated user (e.g., a subscriber) to modify a plugin setting and bypass manual approval of new bookings.
