CVE-2026-87894
UnknownSummary
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. This allows unauthenticated attackers to read any customer's name, email, phone, booking details and payment status by enumerating that identifier.
Risk Assessment
An unauthenticated attacker can obtain personal data and booking details of all customers, which is a serious privacy breach and may result in legal consequences (GDPR). The risk to reputation and compliance is high.
Recommendation
Update the plugin to version 1.2.3 or later to fix the missing authorization check.

The Rox Appointment Booking WordPress plugin before 1.2.0 does not verify the order total or the selected payment method against its own server-side pricing when creating a booking. This allows unauthenticated attackers to create confirmed bookings at an arbitrary price and to bypass the site's configured payment-method restrictions.
- CVE-2026-87891Unknown
The Rox Appointment Booking WordPress plugin before 1.2.0 does not perform any capability or authorization check when saving its holiday schedule.
