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 · moderate confidenceThis is a critical authentication bypass vulnerability in Notes Station 3 where certain functions lack proper authentication checks. Remote attackers can exploit this to access and execute sensitive functions without providing valid credentials, likely through direct API or web requests to unauthenticated endpoints.

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.
-
Confirm Notes Station 3 is installedLog into the QNAP NAS administrative interface, open App Center, and search for Notes Station 3 in the installed applications list.Affected if Notes Station 3 is not found in installed applications, the system is not affected.
-
Identify the installed version of Notes Station 3In App Center, click on Notes Station 3 and view the version information displayed, or check the application details panel.Affected if The displayed version falls within the range 3.9.0 to 3.9.6 (any version >= 3.9.0 but < 3.9.7).
-
Verify network exposure of Notes Station 3 web interfaceAccess the Notes Station 3 web portal by navigating to https://[NAS-IP]:[Port]/notes-station/ or via the QNAP myQNAPcloud link if remote access is configured.Affected if The web interface is accessible over the network and the version is affected, indicating potential exposure to the bypass.
-
Check for unauthenticated API access capabilityAttempt to access common Notes Station 3 API endpoints (such as /api/notes or /api/user) without providing login credentials using a tool like curl or a browser.Affected if API endpoints respond without requiring authentication and the installed version is in the affected range.
The environment is affected if Notes Station 3 is installed with version 3.9.0 through 3.9.6 and the web interface or API is network-accessible.

dbcve · scoped3.9.7
Upgrade Notes Station 3 to version 3.9.7 or later immediately. This is a critical severity issue (CVSS 9.8) that should be prioritized given the availability of a fix.
Notes Station 3 version 3.9.7 or later
- Log in to the QNAP NAS admin console
- Navigate to the App Center or Notes Station 3 application
- Check the current installed version of Notes Station 3
- If the version is between 3.9.0 and 3.9.6 (inclusive), update to version 3.9.7 or later
- Verify the update was successful and confirm the new version is 3.9.7 or higher
