# Azure DevOps Server: authorization bypass lets a user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-85923 (this .md is for agents)

A user-controlled key in Azure DevOps Server bypasses authorization checks. An authorized attacker reaching the server over the network can elevate their privileges.

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

## How to check

Unknown: Microsoft has not been read directly. On the Azure DevOps Server machine, run <patch-installer>.exe CheckInstall with the patch named in the MSRC entry for CVE-2026-85923 to see whether it is installed (command from Microsoft's patch blog posts).
