CVE-2026-50083
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Aqara IAM/SSO Gateway (gw-builder.aqara.com) used a hardcoded OAuth client credential, which is an instance of "CWE-798: Use of Hard-coded Credentials." This issue has an estimated CVSS of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N (9.1 Critical). When combined with CVE-2026-50082, CVE-50084, and CVE-50085, this can lead to a fully unauthenticated, remote takeover of affected devices.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Aqara IAM/SSO Gateway (gw-builder.aqara.com) contains a hardcoded OAuth client credential (CWE-798: Use of Hard-coded Credentials), allowing unauthenticated attackers to obtain valid OAuth tokens. Combined with CVE-2026-50082, CVE-50084, and CVE-50085, this enables fully unauthenticated remote takeover of affected devices.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Aqara IAM/SSO Gateway is presentInventory your environment for instances of the Aqara IAM/SSO Gateway service (gw-builder.aqara.com). Check running processes, installed applications, or container images for this component.Affected if The Aqara IAM/SSO Gateway software is installed or running in your environment.
-
Determine the installed versionLocate the version information for the Aqara IAM/SSO Gateway installation. Common methods include: checking the application About/Version UI, reviewing build metadata, examining the software bill of materials, or querying the service API if version endpoint is exposed.Affected if The installed version matches exactly 2026-04-20.
-
Verify exposure to networkDetermine if the gateway service is accessible from network segments accessible to unauthenticated attackers. Check firewall rules, networkACLs, or VPN configurations that may permit external access to the IAM/SSO Gateway port or endpoint.Affected if The gateway is externally accessible or accessible from untrusted network segments.
-
Audit OAuth token issuance logsReview authentication and OAuth token logs for the gateway, if available. Look for unexpected or unauthorized token issuance events, particularly from sources or patterns inconsistent with legitimate usage.Affected if OAuth tokens were issued to unknown or unexpected sources, indicating potential exploitation of the hardcoded credential.
Your environment is affected if you have the Aqara IAM/SSO Gateway version 2026-04-20 running and accessible to potential attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately rotate the hardcoded OAuth client credential to a dynamically generated, securely stored secret; deploy firmware/software updates to remove embedded credentials; implement proper secrets management with rotation policies.
