## Overview

SQL Chat contains four unauthenticated API endpoints that accept client-supplied database connection parameters and execute arbitrary SQL queries against attacker-specified hosts. Attackers can connect to internal databases, execute SQL commands, enumerate schemas, and pivot into the server's network without authentication.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
