CVE-2026-65824

OpenReception: invite confirmation token is replayable within its validity window and re-issues a registration-bootstrap cookie

Published Oct 23, 2026 CVSS 3.1 · 7.4 High EPSS < 1% KEV · Not listed
Description
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.
