Local information disclosure to low-privileged users
Published Jan 13, 2026 · Updated Jan 13, 2026
Information disclosure in Microsoft Windows Management Services allows local users with low privileges to read sensitive information. Microsoft has not published the affected code path, the data exposed, or the operation that mishandles it. Exploitation requires local low-privilege access and no user interaction; the reported impact is limited to confidentiality, with no integrity or availability effect.
