Apache Superset <6.0.0 SQLLab bypass of read-only check via Improper Input
CVE-2026-23984 Published on February 24, 2026

Apache Superset: SQLLab Read-Only Bypass on PostgreSQL
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.
