# SQL Server: SQL injection lets an authorized user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-118120 (this .md is for agents)

SQL Server does not neutralize special characters in a SQL command, which is a SQL injection flaw. An attacker who already has a valid account can escalate their privileges over the network.

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

## How to check

- Identify SQL Server instances and their versions with `SELECT @@VERSION`
- Check whether the instance is reachable from untrusted networks

## Timeline

## From the sources

Improper neutralization of special elements used in an sql command ('sql injection') in SQL Server allows an authorized attacker to elevate privileges over a network.
