Windows Installer Elevation of Privilege Vulnerability

Exact source revision recorded 11 Nov 2026 02:25:43 UTC. It does not establish the source's current position. Latest evidence.

cve-program · CVE-2026-105545

Published

An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation.
