Authenticated information disclosure via uninitialized resource
Published Sep 8, 2026 · Updated Sep 10, 2026
Use of an uninitialized resource in Microsoft SQL Server 2017 through 2025 allows remote authenticated users to disclose information. Microsoft has not disclosed the affected component, the resource that remains uninitialized, or the request that exposes its contents.
