# MySQL Connector/Net: unauthenticated user can read a subset of data

Oracle's MySQL Connector/Net 26.7.0 has a flaw that lets a remote, unauthenticated attacker read a subset of data the connector can access. Exploitation needs a person other than the attacker to take an action.

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

## How to check

- Run `unknown` to find the installed Connector/Net version in the application's package manifest or NuGet lockfile
- Check whether the application references MySQL.Data or MySqlConnector at version `26.7.0`

## Fix

- Move MySQL Connector/Net off `26.7.0` to the patched release named in Oracle's advisory (version unknown from these sources)
