CVE-2026-54377: VitaFit Cloud API IDOR via profile_id Endpoints

VitaFit cloud API before 2026-10-30 contained an insecure direct object reference vulnerability that allows authenticated attackers to access another user's data by supplying a different userid or profileid to endpoints such as GET /front/profile/{profileid}/report/ and GET /front/profile/{profileid}/bodyindexperday/. Attackers can leverage predictable userid and profileid relationships combined with an account-enumeration weakness to read another account's email address, profile, body-composition report, and measurement history at scale.
