Executive brief
Apache Superset is an open-source business intelligence platform used to create interactive dashboards and analyze data. A vulnerability in the FAB security API allows lower-privilege users (those without role-creation permissions) to create new roles, potentially leading to privilege escalation and unauthorized system changes. This configuration is disabled by default but can be enabled by administrators.
Technical details
An improper authorization vulnerability (CWE-285, CWE-863) exists in Apache Superset's Flask-AppBuilder security API endpoint when the FAB_ADD_SECURITY_API flag is enabled. Lower-privilege users (Gamma users) can invoke the role creation API despite lacking the necessary permissions, bypassing authorization checks. The vulnerability requires network access and an authenticated account, but no admin role is needed. An attacker can exploit this to create arbitrary roles and escalate privileges. The fix is available in version 4.1.0, which properly enforces authorization on the security API endpoints.
