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
An issue was discovered on goTenna Mesh devices with app 5.5.3 and firmware 1.1.12. The verification token used for sending SMS through a goTenna server is hardcoded in the app.

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 goTenna Mesh mobile application (version 5.5.3) contains a hardcoded verification token used for SMS routing through goTenna's servers. This hardcoded credential allows anyone who discovers it to bypass authentication and send SMS messages through the service, potentially impersonating legitimate users or consuming service resources.

MitigationReplace the hardcoded verification token with a dynamic authentication mechanism such as per-session tokens, OAuth-based authentication, or a proper credential management system. Rotate any exposed tokens immediately.

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 mobile application version
    Open the goTenna Mesh app on your device, navigate to Settings > About or App Info, and locate the version number displayed
    Affected if The version shown is exactly 5.5.3 (the affected version)
  2. Check goTenna Mesh firmware version
    Connect your goTenna Mesh device to the mobile app, then go to Settings > Device Info or similar menu to view the firmware version
    Affected if The firmware version displayed is exactly 1.1.12 (the affected version)
  3. Verify if SMS routing is configured
    In the goTenna Mesh app, check Settings > SMS or Messaging settings to see if SMS relay or SMS routing through goTenna servers is enabled
    Affected if SMS routing through goTenna servers is turned on and the app/firmware version matches the affected versions listed above
  4. Inspect network traffic for the hardcoded token
    Use a network proxy tool (such as Burp Suite or mitmproxy) to intercept traffic between the goTenna app and goTenna servers while sending an SMS; look for a static token value in the request headers or body
    Affected if A hardcoded, static token value appears consistently in SMS-related API requests

You are affected if your goTenna Mesh firmware is version 1.1.12 or your mobile app is version 5.5.3, and you have SMS routing through goTenna servers enabled.
