# Windows Task Scheduler: local user can gain elevated privileges

Link for people: https://infrastack.ai/live/CVE-2026-96845 (this .md is for agents)

Windows Task Scheduler has an improper authorization flaw that lets an already-authorized local user elevate their privileges. An attacker with a local account could gain higher system rights on the affected machine.

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

## Affected

- microsoft:Windows 10/11 and Windows Server affected below fixed build per version (see fix) fixed 10.0.14393.9612, 10.0.17763.9376, 10.0.19044.7807, 10.0.19045.7807, 10.0.22631.7652, 10.0.26100.9711, 10.0.26100.33650, 10.0.26200.9711, 10.0.28000.3231, 10.0.26300.9711, 10.0.20348.5761, 6.2.9200.26434, 6.3.9600.23470

## How to check

Run winver or [System.Environment]::OSVersion / (Get-ComputerInfo).OsBuildNumber and compare the full build (e.g. 10.0.26100.x) to the fixed builds listed in the product rows; an installed build below the fixed one is exposed. Confirm the KB in Microsoft's Security Update Guide.

## Fix

Install the November 2026 Windows cumulative update that raises the build to at least: Win10 1607/Server 2016 10.0.14393.9612; 1809/Server 2019 10.0.17763.9376; 21H2 10.0.19044.7807; 22H2 10.0.19045.7807; Win11 23H2 10.0.22631.7652; 24H2/Server 2025 builds 10.0.26100.9711 (Win11) / 10.0.26100.33650 (Server 2025); 25H2 10.0.26200.9711; 26H1 10.0.28000.3231; 26H2 10.0.26300.9711; Server 2022 10.0.20348.5761; Server 2012 6.2.9200.26434; 2012 R2 6.3.9600.23470.
