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 v1 devices with app 5.5.3 and firmware 0.25.5. The app there makes it possible to inject any custom message (into existing v1 networks) with any GID and Callsign via a software defined radio. This can be exploited if the device is being used in an unencrypted environment or if the cryptography has already been compromised.

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

goTenna v1 mesh networking devices with app 5.5.3/firmware 0.25.5 have a message injection vulnerability allowing arbitrary GID and Callsign spoofing via software defined radio. The app does not properly authenticate or validate message origin, enabling an attacker to inject custom messages into existing v1 networks. Exploitation requires either an unencrypted environment or pre-compromised cryptography.

MitigationEnsure goTenna v1 devices operate in encrypted mode only; contact goTenna for firmware updates addressing this vulnerability; if no patch is available, consider replacing affected devices or implementing additional network-layer controls to detect anomalous messages.

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. Verify goTenna firmware version
    Access the device settings or connected app and check the firmware version displayed in the device information or system status area
    Affected if Firmware version is exactly 0.25.5
  2. Verify goTenna app version
    Check the installed application version in the app store listing, app settings 'About' section, or device paired app information
    Affected if App version is exactly 5.5.3
  3. Confirm encryption status
    Inspect the device or app security settings to determine whether encrypted mode is enabled for mesh communications
    Affected if Encryption is disabled or set to unencrypted mode; if encryption is enabled but using potentially compromised cryptographic settings, the device may also be affected

User is affected if their goTenna v1 device runs firmware 0.25.5 paired with app 5.5.3 and operates in an unencrypted configuration or has compromised cryptography, allowing message injection via software defined radio.
