Risk Analysis

The Aqara IAM/SSO gateway (gw-builder.aqara.com) is critically vulnerable, exposing bidirectional AES round-trips against the platform's signing key without authentication. This allows an attacker to interact with critical cryptographic functions without proper authorization. With a CVSS score of 10.0, this flaw represents a severe risk to the system's integrity and confidentiality.

No public exploit is currently known for this vulnerability. The attack vector is network-based and has low complexity, making it remotely exploitable.

Recommended Action

Implement robust authentication for all critical functions on the Aqara IAM/SSO gateway. Review and update cryptographic implementations to use strong, modern algorithms and secure key management practices.

Technical Analysis

CVE-2026-50086 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
