Doc Text:
A flaw was found in the VitaFit cloud API. An authenticated remote attacker can exploit overly permissive Amazon Web Services (AWS) role permissions to upload files across an entire shared Amazon Simple Storage Service (S3) bucket rather than remaining restricted to their designated folder. This allows an attacker to overwrite other users' stored data, leading to unauthorized data modification and loss of original content.

Description OSIDB Bzimport 2026-11-05 22:04:52 UTC
VitaFit cloud API before 2026-10-30 contained an improper access control vulnerability in its Cognito-issued AWS role that allows authenticated attackers to perform s3:PutObject operations across the entire shared bucket instead of being restricted to their own folder. Attackers can overwrite other users' objects in the shared S3 bucket using credentials obtained via CVE-2026-54378, destroying original content without triggering deletion protections.
