CVE-2026-48076Public exploitNetwork attack vector

Unauthorized private-channel booking via missing public check

Published Aug 6, 2026 · Updated Aug 6, 2026

Incorrect authorization in OpenReception 1.0.1 and earlier allows remote attackers to create appointments on private channels. The createNewClientWithAppointment service checks only that a channel is not archived, while its channel-agnostic bootstrap token permits an attacker-supplied channelId. A private channel ID is required; an unauthenticated schedule endpoint exposes those IDs, and repeated bookings can consume available slots.
