## Overview

An Improper Input Validation vulnerability exists in Apache Superset that allows an authenticated user with SQLLab access to bypass the read-only verification check when using a PostgreSQL database connection.
While the system effectively blocks standard Data Manipulation Language (DML) statements (e.g., INSERT, UPDATE, DELETE) on read-only connections, it fails to detect them in specially crafted SQL statements.

This issue affects Apache Superset: before 6.0.0.

Users are recommended to upgrade to version 6.0.0, which fixes the issue.

## Affected packages

- `apache-superset < 6.0.0`

## Remediation

Upgrade to a patched release:

- `apache-superset 6.0.0`
