Description

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.
