CVE-2026-65824

OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 2.2.1, an attacker who captures a pending invite token can replay it to obtain a passkey-registration credential and register their own passkey on the invited account, taking control of that account. For a staff or tenant-admin invite this yields access to the tenant context tied to that account. This issue has been patched in version 2.2.1.
