# Microsoft SQL Server: authorized user can gain higher privileges over network

Link for people: https://infrastack.ai/live/CVE-2026-118111 (this .md is for agents)

An origin validation error in Microsoft SQL Server lets a user who already has an account raise their privileges across the network. The attacker would gain rights beyond what they were granted.

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

## How to check

- Check the SQL Server version with `SELECT @@VERSION` and compare it to the fixed builds listed by Microsoft (unknown from these sources)
- Review which logins hold elevated roles, since an authorized account is the starting point
