Improper Authorization in Apache Superset Dashboard Updates

Publication date: 2026-07-30

Last updated on: 2026-07-30

Assigner: Apache Software Foundation

Description

An Improper Authorization vulnerability exists in Apache Superset allowing an authenticated user with permissions to update charts to modify dashboards they do not own. When updating a chart's properties via the REST API, a user can provide a list of dashboard IDs (dashboards) to associate the chart with. The validation logic in the UpdateChartCommand failed to verify that the user had write permissions for the target dashboards specified in the request body. This issue affects Apache Superset: before 6.0.0. Users are recommended to upgrade to version 6.0.0, which fixes the issue.

Attack-Flow Graph

Executive Summary

This vulnerability in Apache Superset allows an authenticated user with chart update permissions to modify dashboards they do not own. The issue occurs when updating a chart via the REST API, where the user can specify dashboard IDs to associate the chart with. The system fails to check if the user has write permissions for those target dashboards.

Detection Guidance

To detect this vulnerability, check Apache Superset instances for unauthorized dashboard modifications by authenticated users. Review API logs for chart update requests containing unexpected dashboard IDs. Verify user permissions for dashboard write access. Ensure all instances are running version 6.0.0 or later.

Impact Analysis

An attacker with valid credentials could modify dashboards they do not own, potentially altering data visualizations, misleading users, or causing operational disruptions. This could lead to incorrect decision-making based on tampered dashboard content.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by allowing unauthorized users to modify dashboards they do not own. This may lead to unauthorized data access or manipulation, violating data integrity and confidentiality requirements under these regulations.

Mitigation Strategies

Upgrade Apache Superset to version 6.0.0 or later to address the improper authorization issue affecting dashboard permissions.
