Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to version 4.8.3, an unauthenticated attacker can inject arbitrary SQL into queries executed against databases connected to Chartbrew (MySQL, PostgreSQL). This allows reading, modifying, or deleting data in those databases depending on the database user's privileges. This issue has been patched in version 4.8.3.
