CVE-2025-32887
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. A command channel includes the next hop. which can be intercepted and used to break frequency hopping.
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 confidenceThe goTenna v1 mesh networking device (app 5.5.3, firmware 0.25.5) transmits next hop routing information in its command channel. An attacker capable of intercepting this unencrypted or weakly protected channel can extract routing metadata and exploit it to disrupt the frequency hopping spread spectrum (FHSS) mechanism that provides anti-jamming and communication security.

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.
-
Identify device modelLocate the physical goTenna device or check device documentation to confirm it is a goTenna v1 mesh networking unitAffected if Device is a goTenna v1 model
-
Check firmware versionAccess the device settings or companion app and navigate to the firmware version information. On the device, this is typically found under Settings > Device Info > Firmware VersionAffected if Firmware version is exactly 0.25.5
-
Check app versionOpen the goTenna companion mobile application, then go to Settings > About or App Info to view the installed application version numberAffected if App version is exactly 5.5.3
-
Verify command channel is activeMonitor network traffic from the device using a RF sniffer or network analysis tool capable of capturing the command channel. Confirm that unencrypted routing information packets are being transmittedAffected if Command channel is transmitting and routing metadata is visible in plaintext
You are affected if you have a goTenna v1 device running firmware 0.25.5 with app version 5.5.3 and the command channel is actively transmitting routing information

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 dataUpdate to patched firmware versions when available. Until then, minimize use of affected devices in high-security contexts and monitor for anomalous RF activity that could indicate interception attempts.
