CVE-2026-23984

Apache Superset: SQLLab Read-Only Bypass on PostgreSQL

Assigner: apache
Reserved: 19.01.2026 Published: 24.02.2026 Updated: 24.02.2026

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.
