CVE-2025-32881
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 · uneditedAn issue was discovered on goTenna v1 devices with app 5.5.3 and firmware 0.25.5. By default, the GID is the user's phone number unless they specifically opt out. A phone number is very sensitive information because it can be tied back to individuals. The app does not encrypt the GID in messages.
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 goTenna v1 mobile app (v5.5.3) and firmware (v0.25.5) use the user's phone number as the default Group ID (GID) without encryption. This phone number is transmitted in plaintext within messages, allowing interception and correlation of communications to specific individuals.

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.
-
Check goTenna Mesh firmware versionAccess the goTenna Mesh device settings menu and navigate to Device Info or About to view the firmware version numberAffected if Firmware version is exactly 0.25.5
-
Check goTenna mobile app versionOpen the goTenna app on your phone, go to Settings or Account section, and locate the version information under About or App InfoAffected if Mobile app version is exactly 5.5.3
-
Inspect message traffic for plaintext phone numbersUse a network capture tool (such as Wireshark or a mobile proxy) to intercept and inspect outgoing messages from the goTenna app; look for your phone number appearing in plaintext within message payloadsAffected if Your phone number appears in plaintext within captured message data
-
Verify GID configuration in app settingsOpen the goTenna app settings and locate the Group ID (GID) configuration; examine whether the default GID is set to your phone number without encryption enabledAffected if GID is set to your phone number with no encryption applied
You are affected if you are running goTenna Mesh firmware 0.25.5 or goTenna app 5.5.3 and your phone number is visible as the plaintext Group ID in network traffic.

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 dataImplement encryption for the GID field in all messages and change the default behavior to use randomly generated identifiers instead of phone numbers, requiring users to explicitly opt-in to phone number-based GID.
