Unauthorized actions via replayed BLE GATT writes
Published Jul 7, 2026 · Updated Jul 7, 2026
Improper authentication in Fire-Boltt Smartwatch FB BGS001 firmware MOY-JS14-2.0.4 allows physically proximate attackers to trigger functions. BLE GATT Write Request handling accepts previously captured command packets without sufficient authentication or strong session validation. The attack requires prior capture of valid BLE traffic and radio proximity; replayed packets invoke only the smartwatch functionality exposed by those commands.
