Background
Apache Superset is an open-source data visualization and business intelligence tool that allows users to explore and visualize data through a web interface. It supports various databases and provides features such as dashboards, charts, and SQL querying capabilities. However, a vulnerability has been identified that affects its ability to enforce read-only access on PostgreSQL connections, potentially allowing unauthorized data manipulation.
Vulnerability Detail
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. Although 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 oversight can lead to unauthorized data changes, compromising the integrity of the database.
