{"id":"CVE-2026-110124","summary":"FastBee through 2.1.0 IDOR via DeviceController /iot/device Endpoints","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.","modified":"2026-10-15T02:47:30.064530864Z","published":"2026-10-13T16:53:19.145Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110124.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110124.json"},{"type":"ADVISORY","url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/fastbee-device-ownership-idor"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110124"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/fastbee-through-2.1.0-idor-via-devicecontroller-iot-device-endpoints"},{"type":"PACKAGE","url":"https://github.com/kerwincui/FastBee"},{"type":"ARTICLE","url":"https://github.com/kerwincui/FastBee/blob/v1.2.1/springboot/wumei-iot/src/main/java/com/ruoyi/iot/controller/DeviceController.java#L118-L213"},{"type":"ARTICLE","url":"https://github.com/kerwincui/FastBee/blob/v2.1.0/springboot/fastbee-open-api/src/main/java/com/fastbee/data/controller/DeviceController.java#L119-L211"},{"type":"ARTICLE","url":"https://github.com/kerwincui/FastBee/blob/v2.1.0/springboot/fastbee-service/fastbee-iot-service/src/main/java/com/fastbee/iot/service/impl/DeviceServiceImpl.java#L105-L125"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kerwincui/fastbee","events":[{"introduced":"0"},{"fixed":"984a5e6357b644ea9c8624e122521eb91757ee7e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.1.0"},{"fixed":"2.1.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v2.0.1","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110124.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
