# Windows eSCL Scanner: stored credentials are insufficiently protected, letting a local user gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-112801 (this .md is for agents)

Windows eSCL Scanner stores credentials insufficiently protected, so an attacker who already has a local account can read them. The attacker can then elevate privileges on the machine.

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

## Affected

- microsoft:Windows 10 21H2 affected >= 10.0.19044.0, < 10.0.19044.7846 fixed 10.0.19044.7846
- microsoft:Windows 10 22H2 affected >= 10.0.19045.0, < 10.0.19045.7846 fixed 10.0.19045.7846

## How to check

Run winver or [System.Environment]::OSVersion.Version (PowerShell) and compare the full build (e.g. 10.0.26100.9974) with the fixed builds. Below the fixed build = exposed. Microsoft does not say in the record whether eSCL Scanner is on by default; check the update history for the November 2026 cumulative update.

## Fix

Install the November 2026 Windows cumulative update. Fixed builds: Win10 21H2 10.0.19044.7846; Win10 22H2 10.0.19045.7846; Win11 23H2 10.0.22631.7711; Win11 24H2 10.0.26100.9974; Win11 25H2 10.0.26200.9974; Win11 26H1 10.0.28000.3501; Win11 26H2 10.0.26300.9974; Server 2022 10.0.20348.5870; Server 2025 10.0.26100.33822.
