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 · unedited
Aikaan IoT management platform v3.25.0325-5-g2e9c59796 provides a configuration to disable user sign-up in distributed deployments by hiding the sign-up option on the login page UI. However, the sign-up API endpoint remains publicly accessible and functional, allowing unauthenticated users to register accounts via APIs even when the feature is disabled. This leads to authentication bypass and unauthorized access to admin portals, violating intended access controls.

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 confidence

The Aikaan IoT management platform v3.25.0325-5-g2e9c59796 has a access control bypass where disabling user sign-up only hides the UI option on the login page, but the underlying registration API endpoint remains publicly accessible and functional. Unauthenticated attackers can directly invoke the sign-up API to create new accounts, bypassing the intended access restriction and gaining unauthorized access to the platform.

MitigationDisable the sign-up API endpoint server-side when the configuration is set, not just hide the UI. Implement proper authorization checks at the API layer to enforce the registration-disabled setting.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Aikaan version
    Run 'aikaan --version' from command line or check the About/Version page in the web UI to confirm the exact version number
    Affected if Version matches v3.25.0325-5-g2e9c59796 or falls within the same release line (v3.25.x) where this vulnerability was introduced
  2. Verify sign-up is disabled in the UI
    Navigate to the login page of the Aikaan platform and inspect whether the sign-up/register link or button is hidden, removed, or explicitly disabled
    Affected if The sign-up option appears disabled or hidden in the UI (this is the misleading condition the CVE exploits)
  3. Test registration API endpoint directly
    Send a POST request to the registration API endpoint (typically /api/register, /api/signup, or /api/users/create) with a test email and password payload. For example: curl -X POST https://your-aikaan-host/api/register -d '{"email":"[email protected]","password":"TestPass123"}' -H 'Content-Type: application/json'
    Affected if The API accepts the request and returns a success or account-created response (HTTP 200/201) even when sign-up appears disabled in the UI, indicating the API is still publicly accessible

If you can successfully create a new account by calling the registration API directly while the sign-up option is hidden or disabled in the UI, your environment is affected by CVE-2025-52352.
