Local information disclosure
Published Jun 8, 2021 · Updated May 28, 2026
Information disclosure in Microsoft 3D Viewer before 7.2105.4012.0 allows local users to read sensitive data via unspecified vectors. Microsoft has not published the affected component or the operation that exposes data, so the concrete parsing or rendering flaw is undisclosed. Exploitation requires low-privileged local access and user interaction; the published impact is limited to confidentiality, with no integrity or availability effect.
