CVE-2025-32887

Frequency-hopping disruption via exposed next-hop data

Published May 1, 2025 · Updated May 1, 2025

Cleartext transmission in goTenna v1 app 5.5.3 and firmware 0.25.5 allows physically proximate attackers to disrupt frequency hopping. The command channel transmits the next-hop value without confidentiality protection, exposing the information needed to defeat the radio's hopping sequence. An unauthenticated attacker within RF interception range can recover that value and interrupt communications while obtaining limited channel information.
