How the CVE Works
CVE-2025-32884 exposes sensitive user information in goTenna Mesh devices due to unencrypted Group ID (GID) transmission. By default, the GID is set to the user’s phone number unless manually opted out. The app fails to encrypt this GID in messages, allowing attackers intercepting communications to extract phone numbers. This vulnerability stems from insecure data handling in app version 5.5.3 and firmware 1.1.12, enabling potential identity linkage and privacy breaches.
