CVE-2025-32886
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. All packets sent over RF are also sent over UART with USB Shell, allowing someone with local access to gain information about the protocol and intercept sensitive data.
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 confidenceOn goTenna v1 devices (app 5.5.3, firmware 0.25.5), all RF packets are inadvertently duplicated and transmitted over UART with USB Shell. This allows a local attacker with physical access to intercept sensitive communications and analyze the protocol by monitoring the UART output.

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 the goTenna Mesh firmware versionAccess the device settings or connected app interface and locate the firmware version information typically found in device info, about, or system settings menusAffected if The firmware version is exactly 0.25.5
-
Check the goTenna app versionOpen the goTenna mobile application and navigate to the app settings, typically under Settings > About or similar menu path, to view the installed application versionAffected if The app version is exactly 5.5.3
-
Verify if USB Shell access is availableConnect the goTenna device to a computer via USB and attempt to access the device shell or serial interface, often visible as a USB serial device or requiring a terminal connectionAffected if USB shell or UART interface is accessible and responds to commands
-
Confirm RF packet transmission over UARTWith the device connected via USB, monitor the serial/UART output while the device transmits or receives RF packets to observe if packet data is duplicated in the outputAffected if RF packet data appears in the UART/USB shell output in addition to normal operation
A user is affected if their goTenna Mesh firmware is version 0.25.5 AND their app version is 5.5.3, with USB shell/UART access available for packet interception.

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 dataUsers should update to patched firmware versions when released by goTenna. Until then, avoid using the device in untrusted physical environments where UART/USB shell access is possible.
