DescriptionCVE.org

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.

AnalysisAI

Insufficient SQL function restrictions in Apache Superset before 4.1.2 allow authenticated users to execute sensitive database functions on ClickHouse engines that should have been blocked. An attacker with database access could leverage the incomplete DISALLOWED_SQL_FUNCTIONS list to bypass security controls and potentially extract or manipulate data. No patch is currently available for affected versions of Apache Superset, PostgreSQL, and related deployments.
