CVE-2025-32889

SMS service abuse via hardcoded verification token

Published May 1, 2025 · Updated May 1, 2025

Hard-coded credentials in goTenna v1 app 5.5.3 and firmware 0.25.5 allow local users to abuse the SMS service through a reused token. The app embeds a verification token used to authorize SMS requests through a goTenna server instead of obtaining a per-user secret. Local access to the app is required to recover the token, after which the shared credential permits unauthorized SMS requests and service interruption.
