CVE-2026-37271: n/a
The Fire-Boltt Smartwatch FB BGS001 with firmware MOY-JS14-2.0.4 is vulnerable to improper authentication. It accepts GATT Write Request commands without sufficient authentication or strong session validation. This allows an attacker to replay previously captured Bluetooth Low Energy (BLE) packets from a nearby device to trigger smartwatch functionality.
AI Analysis
Technical Summary
CVE-2026-37271 identifies an improper authentication vulnerability in the Fire-Boltt Smartwatch FB BGS001 firmware MOY-JS14-2.0.4. The device does not adequately authenticate GATT Write Request commands, enabling replay attacks using captured BLE packets under specific conditions. This weakness could allow unauthorized triggering of device functionality via BLE communication.
Potential Impact
An attacker in proximity to the smartwatch can replay captured BLE packets to invoke functions on the device without proper authentication. This could lead to unauthorized control or manipulation of smartwatch features. No known exploits are reported in the wild, and the exact impact depends on the functionality accessible via GATT Write Requests.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit physical proximity of untrusted devices to the smartwatch and avoid pairing with unknown BLE devices. Monitor vendor communications for firmware updates addressing this issue.
