Summary
OpenReception, an appointment booking platform with end-to-end encrypted client data, is affected in versions 2.1.0 and earlier. An attacker can guess a returning client's six-digit booking PIN in another tenant because a throttle record in one tenant disables the brute-force protection for the same identifier in a different tenant, potentially giving them access to that client's encrypted appointments and the ability to add or cancel appointments as that client.

Read the original description
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. In versions 2.1.0 and prior, a returning client's six-digit booking PIN can be brute-forced online in the victim tenant. A successful guess yields the client's booking access token, granting access to that client's appointment tunnel, which holds their end-to-end-encrypted appointment data, and the ability to act as the client, for example adding or cancelling appointments in the tunnel. The bypass is cross-tenant: state owned by one tenant removes an authentication protection of a different tenant. This crossing of the tenant boundary is the basis for the scope-changed vector. At time of publication, there are no publicly available patches.
