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.
CVSS 7.7 (HIGH)

Evidence context and dated references

Reality is general threat/review priority, combining observed exploitation, CVSS severity and fresh EPSS. Evidence confidence is separate. This is not calibrated risk, a victim count or an asset-specific assessment. A range reflects missing numeric inputs. Published 2 days ago. Exploitation evidence usually takes weeks to show up: a low reality score can mean there is no data yet, not that the flaw is mild.
