Description
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.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
The records we use list no fixed release for CVE-2026-54382. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
