VitaFit cloud API versions released prior to 2026-10-30 contained a cloud storage bucket misconfiguration. This vulnerability permitted unauthenticated attackers to perform directory listing and file retrieval operations against the bucket without requiring valid authentication credentials. The misconfiguration exposed 129,947 objects, including 126,881 user-uploaded profile images, potentially leaking sensitive personal information.
Impact
The vulnerability allowed unauthorized access to 129,947 total objects within the misconfigured storage bucket. Verified exposure includes the unauthorized retrieval of 126,881 user-uploaded profile images.
Recommendation
- Verify that all cloud storage buckets associated with the VitaFit environment have been audited for public read/list permissions as of 2026-10-30.
- Review cloud provider audit logs (e.g., AWS CloudTrail, GCP Cloud Audit Logs, or Azure Monitor) for high volumes of "ListBucket" or "GetObject" API requests originating from unauthorized or anomalous IP addresses to detect potential data exfiltration.
Immediate actions
Audit cloud infrastructure access policies to ensure no buckets are publicly accessible.
Threat Hunt
Identify anomalous spikes in object storage read/list operations in cloud audit logs.
Data: Cloud provider object storage access logs (e.g., S3 Access Logs, Storage Read Logs)
Mitigations
Ensure all VitaFit cloud API deployments are updated to the post-2026-10-30 configuration.
