CVE-2026-23969 PUBLISHED

Apache Superset: Exposure of Sensitive Information via Incomplete ClickHouse Function Filtering

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

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.
