Executive brief
Apache Superset is a popular open-source data visualization and exploration platform used by organizations to analyze and visualize data. An authentication bypass vulnerability allows low-privileged users with dataset and chart permissions to access unauthorized data by overwriting SQL queries in existing datasets, potentially exposing sensitive business intelligence and customer data to unauthorized employees or accounts.
Technical details
The vulnerability is an improper authorization flaw (CWE-863) in Apache Superset's dataset access control mechanism. An authenticated attacker with permissions to write datasets and read charts can bypass data access controls by modifying the SQL query of an existing dataset, circumventing the permission checks that normally prevent querying unauthorized data sources. The attack requires valid credentials and appropriate dataset/chart permissions but no additional user interaction. An attacker can execute arbitrary queries against connected databases to extract sensitive data. The issue affects all versions before 6.0.0; users should upgrade to version 6.0.0 or later to remediate.
