# WatchGuard Endpoint Protection: local user can gain SYSTEM privileges

Link for people: https://infrastack.ai/live/CVE-2026-57907 (this .md is for agents)

A flaw in how WatchGuard Endpoint Protection's console and protection service talk to each other lets a low-privileged local user inject code into the trusted console process. From there the user can send privileged commands to the service and run arbitrary code with SYSTEM rights.

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

## Affected

- vendor:WatchGuard Endpoint Protection affected range not listed fixed no fixed version listed
- vendor:WatchGuard Endpoint Security (Windows protection) affected >= 0, < 8.00.26.0011 fixed 8.00.26.0011

## How to check

- On each Windows endpoint, check the installed WatchGuard Endpoint Security protection version (About screen or installed programs list). Versions below 8.00.26.0011 are affected.
- In the WatchGuard Cloud console, check the protection version reported per computer.

## Fix

Update WatchGuard Endpoint Security Windows protection to 8.00.26.0011 or later (8.00.26.0012 is the newer release per WatchGuard release notes).

## From the sources

A privilege escalation vulnerability in WatchGuard Endpoint Protection's inter-process communication between the console and the protection service allows a local, low-privileged authenticated user to execute arbitrary code with SYSTEM privileges by injecting code into the trusted console process and issuing privileged commands to the service.
