CVE-2022-0482Public exploitNetwork attack vector

Unauthenticated appointment data disclosure via backend API

Published Mar 9, 2022 · Updated Aug 2, 2024

Incorrect authorization in Easy!Appointments before 1.4.3 allows remote attackers to read private appointment data through its backend API. The public booking form supplies a CSRF token accepted by /index.php/backend_api/ajax_get_calendar_events, which performs no authentication or permission check before returning JSON. No account or user interaction is required, and a chosen date range exposes customers' and appointments' private details.
