Summary
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.
