CVE-2026-109570
Fire-Boltt BSW013 smartwatch firmware through V0.0.8 contains a missing authentication vulnerability that allows unpaired attackers to inject notifications by writing to the proprietary BLE command characteristic.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
Fire-Boltt BSW013 smartwatch firmware through V0.0.8 contains a missing authentication vulnerability that allows unpaired attackers to inject notifications by writing to the proprietary BLE command characteristic. Attackers within Bluetooth range can craft commands protected only by a CRC-16/ARC checksum to vibrate the watch and display spoofed alert text for phishing.
