CVE-2026-65824 Details
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.
A vulnerability in OpenReception's appointment booking software prior to version 2.2.1 allows an attacker to replay a captured pending invite token within its 30-minute validity window. This replay can be used to obtain a passkey-registration credential, which can then be used to register a passkey on the invited account, effectively taking control of that account. For staff or tenant-admin invites, this access includes the tenant context associated with the account.
Users should update to OpenReception appointment booking software version 2.2.1 or later, where this vulnerability has been patched.
