Booking for Appointments and Events Calendar vulnerabilities

The Booking for Appointments and Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple Elementor widgets in versions up to and including 2.4.9. This is due to insufficient input sanitization and output escaping on the 'load_manually' parameter in the render() methods of classes. An authenticated attacker with Contributor-level access and above who can use Elementor can inject arbitrary web scripts into pages that execute whenever a user accesses an injected page.

The Booking for Appointments and Events Calendar WordPress plugin before version 2.4.9 does not require authentication or a valid request token before running the post-booking action chain, allowing an unauthenticated user to trigger booking notifications and integration callbacks for a booking by enumerating its identifier.

The Booking for Appointments and Events Calendar WordPress plugin before 2.4.9 does not check that a user holds the required capability before letting them change an appointment's status, allowing customers to set arbitrary statuses on appointments they are booked on, including approving their own bookings that were left awaiting approval and overwriting another customer's booking status on a shared appointment.

The Booking for Appointments and Events Calendar WordPress plugin before version 2.4.7 does not require authentication before processing its pending notification queue, allowing an unauthenticated user to force the dispatch of queued notifications and integration callbacks.

The Booking for Appointments and Events Calendar WordPress plugin before version 9.8 does not verify that an authenticated employee (provider) owns the provider account being updated. This allows any employee with an Employee Panel login to overwrite another employee's cabinet password and take over their account.

The Booking for Appointments and Events Calendar WordPress plugin before version 2.4.6 does not verify that an authenticated employee (provider) is assigned to the appointment being accessed, allowing any employee to read any appointment by its identifier and disclose the booked customer's personal data.

The Booking for Appointments and Events Calendar WordPress plugin before version 2.4.4 does not restrict which fields can be written during customer import. A user with the Amelia Manager role can modify arbitrary columns of any stored user record by supplying them in the import request.
