# Windows Installer: type confusion lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-96028 (this .md is for agents)

Windows Installer mishandles a resource of an incompatible type, so an attacker with a local account can raise their privileges. The sources give no further detail on the exact trigger.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Open the Microsoft Security Update Guide entry for CVE-2026-96028, find your Windows version in the table and note the KB listed.
- Run winver (or PowerShell Get-HotFix) and check that this KB, or a later cumulative update, is installed.
- Windows Update history should show the November 2026 (2026-11-10) cumulative update.
