Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker to execute potentially harmful SQL functions in Apache Superset when using the ClickHouse database, due to an incomplete list of restricted functions. To exploit this, the attacker needs access to SQL Lab or charts in a version of Superset prior to 4.1.2.

Technical 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.

Related Vulnerabilities

CVE-2025-66249Medium

This vulnerability allows an attacker to access files outside of the intended directory on an Apache Livy server, potentially exposing sensitive data. It can only be exploited if the server is configured with a non-default setting for local directory access, so users should upgrade to version 0.9.0 to protect against this risk.

CVE-2025-60012Medium

This vulnerability allows an attacker to access files they shouldn't be able to reach by sending specially crafted requests to Apache Livy's REST or JDBC interface. To exploit this, the attacker must already have access to these interfaces and be able to include specific Spark configuration values in their requests.

CVE-2026-25604Medium

An attacker could gain unauthorized access to different AWS instances by reusing SAML authentication responses from other instances, potentially bypassing access controls. This vulnerability occurs because the system does not verify the origin of the SAML response against the actual instance URL, so it's crucial to upgrade to version 9.22.0 of the provider if you're using AWS Auth Manager.

CVE-2025-69219High

This vulnerability allows an attacker with access to the database to run unauthorized code, effectively giving them the same permissions as the original creator of workflows in Airflow. While direct access to the database is uncommon and not recommended, upgrading to version 6.0.0 of the provider is essential to eliminate this risk.

CVE-2026-24713Critical

This vulnerability allows an attacker to send malicious input to Apache IoTDB, potentially leading to unauthorized access or manipulation of data. It affects versions 1.0.0 to 1.3.6 and 2.0.0 to 2.0.6, so users should upgrade to the latest versions to protect against this risk.
