CVE-2026-65825 - OpenReception: one tenant's throttle row disables the PIN brute-force throttle for the same identifier in other tenants
CVE ID :CVE-2026-65825
Published : Oct. 23, 2026, 9:17 p.m. | 5 hours, 4 minutes ago
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.
Severity: 7.5 | HIGH
