The Aqara Board service (op-test.aqara.com) accepts arbitrary MQTT command payloads, and forwards them to the platfom's HiveMQ broker without authentication. This is an instance of "CWE-306: Missing Authentication for Critical Function" and has an estimated CVSS ofCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L (8.6 High). When combined with CVE-2026-50082, CVE-50083, and CVE-50084, this can lead to a fully unauthenticated, remote takeover of affected devices.
