CriticalCVSS 9.6
Published: Translated: NVD NIST

Summary

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.

Risk Assessment

The vulnerability enables unauthorized cross-user data access and manipulation. The risk affects the confidentiality and integrity of files stored in the cloud by VitaFit users.

Recommendation

Apply a fix on the VitaFit API side that scopes AWS credentials to the user's own resources. Also rotate any exposed temporary credentials and audit bucket access.
