Vulnerability from github – Published: 2026-10-13 18:30 – Updated: 2026-10-13 18:30

Details

FastBee through 2.1.0 contains an insecure direct object reference vulnerability in DeviceController that allows authenticated low-privilege users to read and modify other tenants' devices by supplying sequential device IDs. Self-registered attackers can enumerate deviceId or serialNumber values to read owner, IP, and location data, and overwrite user_id and tenant_id to take over devices.

Severity

8.1 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
