Technical details
The vulnerability is an information disclosure caused by incomplete authorization logic. The `/api/tenants/{id}/schedule` endpoint filters channels only by pause status and archive flag, but fails to check the `isPublic` flag despite the `addAppointmentToTunnel` endpoint enforcing it. An unauthenticated attacker can send a GET request with arbitrary date ranges to receive all non-archived channels with complete metadata including channel IDs, names, descriptions, assigned agents, and computed slot availability. The issue was fixed in version 1.0.5 by adding the missing `isPublic` filter. No authentication is required for exploitation.
