Technical details
The VitaFit cloud API contains an insecure direct object reference (IDOR) in endpoints such as GET /front/profile/{profile_id}/report/ and GET /front/profile/{profile_id}/body_index_per_day/. Authenticated attackers can substitute arbitrary user_id or profile_id values to access another user's data; the API fails to enforce proper authorization checks. Predictable ID sequences and an account-enumeration weakness allow systematic discovery and enumeration of user accounts and their sensitive health information.
