A 2025 cluster names Hub M2 firmware 4.3.6_0027 directly: undocumented remote access (CVE-2025-65294, CVSS 9.8), command injection, missing server-certificate validation and an unsigned/weak firmware-update path (CVE-2025-65295).

No Aqara product is listed in CISA KEV and no public in-the-wild exploitation of the M2 cluster was identified.
|
| Updatability
|
Very common
|
—
|
Firmware is updated over the air from the Aqara Home app, though the update process itself was found to lack integrity enforcement (CVE-2025-65295).

Hub exposes child devices to Apple HomeKit, Alexa, Google Assistant and Matter-style ecosystems with per-ecosystem pairing.

|
Encrypted with obselete encryption

|
Cloud traffic is TLS-based but Hub M2 firmware failed to validate server certificates (CVE-2025-65290/65291), which downgrades the effective transport protection.

Encrypted with obselete encryption

Keys are held in onboard flash with legacy protection, and the hub was found collecting and uploading data without adequate disclosure (CVE-2025-65297).

Comment
|
| Account management
|
Basic
|
—
|
Aqara Home account with region-scoped homes and member sharing; role granularity and recovery controls are limited.
|
| Authentication
|
Basic
|
—
|
Password-based app login and local pairing; the undocumented remote access path in CVE-2025-65294 shows authentication is not uniformly enforced.
|
| Brute-force protection
|
Basic
|
—
|
Cloud login has basic rate limiting; local interfaces have no documented lockout policy.
|
| Event logging
|
Partial logging
|
—
|
The app shows device/automation history and alarms; authentication events are not exposed as an audit trail.
|
| Passwords
|

—
|
An account password is set at registration and pairing codes expire, but complexity enforcement is minimal.

Reasoning: The M2 is a capable multi-protocol hub but its 2025 CVE cluster is unusually specific and severe for a consumer device: undocumented remote access, command injection, missing certificate validation and an update path without integrity enforcement. Ecosystem integration (HomeKit/Alexa/Google) is broad, which is also a wide authentication surface. Scope note: rated on firmware 4.3.6_0027 as published; a later firmware that fixes the 2025 cluster could raise the device and system criteria. Release date is the M2 launch (year/month precision).
