Apache Superset: Read-Only Bypass via Improper Input Validation on PostgreSQL Connections

Quick fix

PYSEC-2026-2376 — apache-superset: upgrade to the fixed version with the command below.

pip install --upgrade 'apache-superset>=6.0.0'

Details

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.
