This is due to two compounding weaknesses: (1) a non-user-bound `public_nonce` is exposed to unauthenticated users through the public `/wp-json/ssa/v1/embed-inner` REST endpoint, and (2) the `get_item()` method in `SSA_Settings_Api` relies on `nonce_permissions_check()` for authorization (which accepts the public nonce) but does not call `remove_unauthorized_settings_for_current_user()` to filter restricted fields. This makes it possible for unauthenticated attackers to access admin-only plugin settings including the administrator email, phone number, internal access tokens, notification configurations, and developer settings via the `/wp-json/ssa/v1/settings/{section}` endpoint. The exposure of appointment tokens also allows an attacker to modify or cancel appointments."}, {"lang": "es", "value": "El plugin Appointment Booking Calendar \u2014 Simply Schedule Appointments para WordPress es vulnerable al acceso no autorizado de datos sensibles en todas las versiones hasta la 1.6.9.29 inclusive.
