CVE-2025-32884

Phone-number disclosure via cleartext GID transmission

Published May 1, 2025 · Updated May 1, 2025

Cleartext transmission in goTenna Mesh app 5.5.3 and firmware 1.1.12 allows physically proximate attackers to read phone-number GIDs from messages. The app inserts the default GID, which is the user's phone number unless changed, into transmitted messages without encryption. An observer within radio range needs no account or user interaction and can associate captured identifiers with individuals, with no reported integrity or availability impact.
