CVE-2026-23969
Received Received - Intake
Incomplete SQL Function Restrictions in Apache Superset Before

Publication date: 2026-02-24

Last updated on: 2026-02-26

Assigner: Apache Software Foundation

Description
Apache Superset utilizes a configurable dictionary, DISALLOWED_SQL_FUNCTIONS, to restrict the execution of potentially sensitive SQL functions within SQL Lab and charts. While this feature included restrictions for engines like PostgreSQL, a vulnerability was reported where the default list for the ClickHouse engine was incomplete. This issue affects Apache Superset: before 4.1.2. Users are recommended to upgrade to version 4.1.2, which fixes the issue.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability exists in Apache Superset versions before 4.1.2, where the configurable dictionary DISALLOWED_SQL_FUNCTIONS, designed to restrict execution of sensitive SQL functions, had an incomplete default list for the ClickHouse engine.

Because of this incomplete restriction, potentially sensitive SQL functions could be executed in SQL Lab and charts when using ClickHouse, bypassing intended security controls.

Impact Analysis

The impact of this vulnerability is that users of Apache Superset with the ClickHouse engine could execute sensitive SQL functions that were supposed to be blocked.

This could lead to unauthorized data access or manipulation within SQL Lab and charts, potentially exposing sensitive information or affecting data integrity.
