    CVE-2026-54378

    VitaFit cloud API before 2026-10-30 contained a broken access control vulnerability that allows any authenticated user to obtain temporary AWS credentials by calling the POST /front/user/s3/token/ endpoint. Attackers can use these improperly scoped credentials to list the shared storage bucket and read or overwrite other users' stored files, enabling unauthorized cross-user data access and manipulation.
