CVE-2026-17020: CWE-639 Authorization Bypass Through User-Controlled Key in Salon Booking System
The Salon Booking System WordPress plugin through 10.30.33 does not verify that a requested booking belongs to the caller on one of its REST API endpoints, requiring only a basic read capability, allowing any authenticated user (including a Subscriber or self-registered customer account) to disclose any customer's booking personal data such as name, email, phone number, address and private notes by enumerating booking identifiers.
AI Analysis
Technical Summary
The Salon Booking System WordPress plugin versions up to 10.30.33 contain an authorization bypass vulnerability (CWE-639) in one of its REST API endpoints. The endpoint fails to verify ownership of booking data when accessed, requiring only basic read capability. Consequently, any authenticated user, including low-privilege roles like Subscribers or self-registered customers, can enumerate booking identifiers and retrieve personal data of other customers without proper authorization.
Potential Impact
An attacker with any authenticated user account can disclose sensitive personal information of other customers, including names, email addresses, phone numbers, physical addresses, and private notes associated with bookings. This leads to a breach of confidentiality and privacy for affected users.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the REST API endpoints to trusted roles only or disable the vulnerable endpoints if possible.
