Low risk22th percentile - higher than 22% of all known CVEs
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.
Risk Assessment
The risk includes unauthorized access to device data (owner, IP, location) and potential device takeover by overwriting user_id and tenant_id, potentially compromising integrity and confidentiality.
Recommendation
Upgrade FastBee to a fixed version and implement authorization-based access controls for device operations.

See all- CVE-2026-120274Medium
A vulnerability was identified in beecue FastBee up to version 2.1.0. An unknown functionality of the /iot/script file in the Groovy Script Executor component allows code injection. The attack can be carried out remotely, and a patch is available under identifier 890a33846005a937a58cccd738b7fb9821b82ea9.
- CVE-2026-111654Medium
FastBee through 2.1.0 contains an insecure direct object reference vulnerability that allows authenticated low-privilege users to access other users' device groups because GroupController queries lack owner checks. Attackers, including self-registered users, can supply sequential group IDs to read, overwrite, reassign, rewrite device associations of, or delete other users' groups.
- CVE-2026-7677Low
A vulnerability was determined in kerwincui FastBee up to 1.2.1 in the Add function of SysNoticeController.java within the System Notice Handler. Manipulating the noticeContent argument causes cross-site scripting. The attack can be initiated remotely, the exploit has been publicly disclosed and may be utilized, and the vendor did not respond.
- CVE-2026-7676Medium
In kerwincui FastBee up to 1.2.1, the ToolController.download function in ToolController.java of the Tool Download Endpoint component, when manipulating the fileName argument, leads to path traversal. The attack can be performed remotely and the exploit has been publicly disclosed. The vendor did not respond to the disclosure.
Original NVD description (English source)
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.
