## Technical details

The vulnerability is an authorization bypass (CWE-200) affecting the plugin's REST API endpoints for service and category records. The vulnerable endpoints lack authentication and authorization checks, allowing unauthenticated attackers to directly query and retrieve sensitive internal notes associated with booking services and categories. The attack requires only network access to the WordPress installation; no special preconditions or user interaction is needed. An attacker can read private internal notes that were intended to be viewable only by authenticated administrators. The vulnerability is patched in version 1.2.8.
