How the CVE Works
CVE-2025-32885 exploits a flaw in goTenna v1 devices running app version 5.5.3 and firmware 0.25.5. Attackers can use a software-defined radio (SDR) to inject malicious messages into existing v1 networks by spoofing arbitrary Group IDs (GIDs) and Callsigns. This occurs when the device operates in an unencrypted mode or if cryptographic protections are already bypassed. The injected messages can disrupt communications, spread misinformation, or execute unauthorized commands within the mesh network.
