CVE-2026-48078
OpenReception's schedule endpoint discloses isPublic=false channels and slot availability to unauthenticated callers
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.5, the unauthenticated /api/tenants/{id}/schedule endpoint returns every non-archived channel for a tenant regardless of the channel's isPublic flag. Channels marked isPublic = false are intended to be invisible to public callers; the dashboard creates them deliberately to hide internal-only services from the patient booking UI. The schedule endpoint ignores the flag entirely and discloses channel names, descriptions, IDs, agent associations, pause status, confirmation requirements, and computed slot availability for the requested date range. The asymmetry between addAppointmentToTunnel (which enforces eq(channel.isPublic, true)) and the schedule endpoint (which does not) confirms the design intent: private channels exist as a real access boundary in the booking flow, just not in the schedule disclosure. Version 1.0.5 patches the issue.
