CVE-2026-87894 Details
Description
The Rox Appointment Booking WordPress plugin before 1.2.3 does not perform any authorization check on the endpoint that returns a booking's confirmation details, and each booking is addressed by a sequential numeric identifier, allowing unauthenticated attackers to read any customer's name, email, phone, booking details and payment status by enumerating that identifier.
A vulnerability in the Rox Appointment Booking WordPress plugin, affecting versions prior to 1.2.3, allows unauthenticated attackers to access personal information of customers, including names, email addresses, phone numbers, booking details, and payment statuses. This is possible because the plugin's endpoint for booking confirmation details lacks authorization checks, and bookings are identified by sequential numeric identifiers. Attackers can exploit this by enumerating the identifiers to retrieve information.
Users are advised to update the Rox Appointment Booking WordPress plugin to version 1.2.3 or later.
