CVE-2026-87894: CWE-639 Authorization Bypass Through User-Controlled Key in Rox Appointment Booking
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.
AI Analysis
Technical Summary
The Rox Appointment Booking WordPress plugin before version 1.2.3 contains an authorization bypass vulnerability (CWE-639) due to missing authorization checks on the endpoint that returns booking confirmation details. Each booking is referenced by a sequential numeric identifier, enabling unauthenticated attackers to enumerate these identifiers and retrieve sensitive customer data such as names, emails, phone numbers, booking details, and payment status without authentication.
Potential Impact
Unauthenticated attackers can access sensitive personal and booking information of any customer by enumerating booking IDs. This leads to a breach of customer privacy and potential exposure of payment status information. There is no indication of remote code execution or system compromise, but the exposure of personal data can have serious privacy and compliance implications.
Mitigation Recommendations
Upgrade the Rox Appointment Booking plugin to version 1.2.3 or later, where authorization checks on the booking confirmation endpoint have been implemented. Until the update is applied, restrict access to the endpoint if possible or disable the plugin to prevent unauthorized data disclosure.
