Description
Fire-Boltt BSW013 smartwatch firmware through V0.0.8 contains a missing authentication vulnerability that allows unpaired BLE devices to subscribe to the Heart Rate Measurement characteristic (0x2A37). Attackers within Bluetooth range can receive the wearer's live heart rate readings without pairing, bonding, or any confirmation on the watch.
