CVE-2026-23981: Apache Superset: Improper Authorization in Chart Update allowing Dashboard Modification

[Daniel Gaspar <dpgaspar () apache org>]

Severity: 

Affected versions:

- Apache Superset 0.0.0 before 6.0.0

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.
