Authenticated information disclosure via insecure resource default
Published Mar 5, 2026 · Updated Mar 5, 2026
Information disclosure in Microsoft ACI Confidential Containers allows remote authenticated users to read protected data over a network. Azure Compute Gallery initializes a resource with an insecure default, but Microsoft has not identified the resource or disclosed which default exposes the data. Low-privileged access is required; the reported consequence is confidentiality loss without data modification or service interruption.
