{"id":"CVE-2026-111654","summary":"FastBee through 2.1.0 IDOR via /iot/group By-ID Endpoints","details":"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.","modified":"2026-10-21T02:55:48.223897039Z","published":"2026-10-16T17:39:20.715Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111654.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111654.json"},{"type":"PACKAGE","url":"https://github.com/kerwincui/FastBee"},{"type":"ARTICLE","url":"https://github.com/kerwincui/FastBee/blob/v2.1.0/springboot/fastbee-open-api/src/main/java/com/fastbee/data/controller/GroupController.java#L70-L137"},{"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/GroupServiceImpl.java#L37-L143"},{"type":"ARTICLE","url":"https://github.com/kerwincui/FastBee/blob/v2.1.0/springboot/fastbee-service/fastbee-iot-service/src/main/resources/mapper/iot/GroupMapper.xml#L36-L109"},{"type":"ADVISORY","url":"https://hackmd.io/@hieuPenguinnn/fastbee-device-group-cross-user-idor"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111654"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/fastbee-through-2.1.0-idor-via-iot-group-by-id-endpoints"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kerwincui/fastbee","events":[{"introduced":"0"},{"last_affected":"984a5e6357b644ea9c8624e122521eb91757ee7e"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"last_affected":"2.1.0"}]}]}}],"versions":["v2.1.0","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-2026-111654.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:L/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
