CVE-2026-37271: n/a
Fire-Boltt Smartwatch FB BGS001 Firmware: MOY-JS14-2.0.4 is vulnerable to Improper Authentication, The device accepts GATT Write Request commands without sufficient authentication or strong session validation. Under specific conditions, previously captured BLE packets can be replayed from a nearby device to trigger functionality on the smartwatch.
AI Analysis
Technical Summary
CVE-2026-37271 describes an improper authentication vulnerability in Fire-Boltt Smartwatch FB BGS001 Firmware MOY-JS14-2.0.4. The device does not adequately authenticate GATT Write Request commands over Bluetooth Low Energy (BLE), allowing replay of captured BLE packets to invoke functionality without proper authorization. This weakness stems from insufficient session validation and lack of strong authentication mechanisms for BLE commands.
Potential Impact
Successful exploitation allows an unauthenticated attacker within BLE range to replay captured commands and trigger potentially harmful or unauthorized actions on the smartwatch. The vulnerability impacts confidentiality, integrity, and availability, as indicated by the CVSS vector (C:H/I:H/A:H). No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented. Until a patch is available, limit physical proximity of untrusted devices to the smartwatch and consider disabling BLE when not in use.
