Risk Analysis
The Aqara Cloud OAuth Authorization Endpoint (open-cn.aqara.com/oauth/authorize) is critically vulnerable to a redirect bypass due to insufficient validation of domain matching. This flaw, with a CVSS score of 9.3, could allow an attacker to redirect users to malicious sites, potentially leading to credential theft or other phishing attacks.
No public exploit is currently known for this vulnerability. While user interaction is required, the attack vector is network-based and has low complexity.
Users should exercise caution when clicking on links, especially those related to authentication. Developers should implement strict validation of redirect URIs to prevent unauthorized redirection.
Technical Analysis
CVE-2026-50090 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
