How the CVE Works
CVE-2025-32886 affects goTenna v1 devices running app version 5.5.3 and firmware 0.25.5. The vulnerability arises because all RF (Radio Frequency) packets transmitted by the device are also duplicated over UART (Universal Asynchronous Receiver-Transmitter) via USB Shell. This design flaw allows an attacker with physical access to intercept sensitive data, including protocol details and communication content, by monitoring the UART interface. The exposure of this data could facilitate further attacks, such as protocol reverse-engineering or unauthorized data collection.
