# Windows Remote Desktop Gateway: use-after-free lets an authorized user run code

Link for people: https://infrastack.ai/live/CVE-2026-69565 (this .md is for agents)

Use-after-free in the Remote Desktop Gateway Service lets an already-authorized low-privilege user run code locally (CVSS 3.1 7.0, AV:L/AC:H/PR:L). Microsoft has fixed builds for Windows Server 2016, 2019, 2022 and 2025. Not network-reachable by this CVE's own vector; no exploitation or public PoC reported.

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

## Affected

- vendor:Windows Server 2016 affected >= 10.0.14393.0, < 10.0.14393.9688 fixed 10.0.14393.9688
- vendor:Windows Server 2019 affected >= 10.0.17763.0, < 10.0.17763.9487 fixed 10.0.17763.9487
- vendor:Windows Server 2022 affected >= 10.0.20348.0, < 10.0.20348.5870 fixed 10.0.20348.5870
- vendor:Windows Server 2025 affected >= 10.0.26100.0, < 10.0.26100.33822 fixed 10.0.26100.33822

## How to check

On a Windows Server with the RD Gateway role (Get-WindowsFeature RDS-Gateway), run winver or [System.Environment]::OSVersion and compare the build (major.UBR) with the fixed builds above.

## Fix

Install the November 2026 Windows Server cumulative update: builds 10.0.14393.9688 (2016), 10.0.17763.9487 (2019), 10.0.20348.5870 (2022), 10.0.26100.33822 (2025). Confirm on the MSRC page.
