Summary

The Easy Appointments WordPress plugin before 3.12.28 does not require a sufficient capability on one of its appointment-listing REST endpoints, restricting it only to a capability that every authenticated user holds, allowing users with subscriber-level access to read all bookings on the site, including customer names, schedules, and statuses.
