# Windows Print Spooler: local user can gain elevated privileges

Link for people: https://infrastack.ai/live/CVE-2026-119939 (this .md is for agents)

Improper privilege management (CWE-73) in Windows Print Spooler components lets a local user with a low-privilege account gain higher privileges. CVSS 7.8. No exploitation known; not in CISA KEV at publication (2026-11-10).

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

## Affected

- microsoft:Windows 10/11 affected Win10 1607 < 10.0.14393.9688; 1809 < 10.0.17763.9487; 21H2 < 10.0.19044.7846; 22H2 < 10.0.19045.7846; Win11 23H2 < 10.0.22631.7711; 24H2 < 10.0.26100.9974; 25H2 < 10.0.26200.9974; 26H1 < 10.0.28000.3501; 26H2 < 10.0.26300.9974 fixed 10.0.14393.9688, 10.0.17763.9487, 10.0.19044.7846, 10.0.19045.7846, 10.0.22631.7711, 10.0.26100.9974, 10.0.26200.9974, 10.0.28000.3501, 10.0.26300.9974
- microsoft:Windows Server affected 2016 < 10.0.14393.9688; 2019 < 10.0.17763.9487; 2022 < 10.0.20348.5870; 2025 < 10.0.26100.33822 fixed 10.0.14393.9688, 10.0.17763.9487, 10.0.20348.5870, 10.0.26100.33822

## How to check

Run winver and compare the build with the fixed builds. Fixed: Win10 1607/Server 2016 10.0.14393.9688; 1809/Server 2019 10.0.17763.9487; Win10 21H2 10.0.19044.7846; 22H2 10.0.19045.7846; Win11 23H2 10.0.22631.7711; Win11 24H2 10.0.26100.9974; 25H2 10.0.26200.9974; 26H1 10.0.28000.3501; 26H2 10.0.26300.9974; Server 2022 10.0.20348.5870; Server 2025 10.0.26100.33822. Get-Service Spooler shows whether the service runs; whether that is required for exploitation is not stated by the sources I could read.

## Fix

Install the November 2026 Windows cumulative update that brings the build to at least the fixed build for your version (see how-to-check). KB numbers not confirmed.
