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. All superset installations should always set a unique secure random SECRET_KEY. Your SECRET_KEY is used to securely sign all session cookies and encrypting sensitive information on the database. Add a strong SECRET_KEY to your `superset_config.py` file like: SECRET_KEY = <YOUR_OWN_RANDOM_GENERATED_SECRET_KEY> Alternatively you can set it with `SUPERSET_SECRET_KEY` environment variable.

An authenticated user with Gamma role authorization could have access to metadata information using non trivial methods in Apache Superset up to and including 2.0.1

A malicious actor who has been authenticated and granted specific permissions in Apache Superset may use the import dataset feature in order to conduct Server-Side Request Forgery attacks and query internal resources on behalf of the server where Superset is deployed. This vulnerability exists in Apache Superset versions up to and including 2.0.1.

When explicitly enabling the feature flag DASHBOARD_CACHE (disabled by default), the system allowed for an unauthenticated user to access dashboard configuration metadata using a REST API Get endpoint. This issue affects Apache Superset version 1.5.2 and prior versions and version 2.0.0.

An authenticated attacker with update datasets permission could change a dataset link to an untrusted site, users could be redirected to this site when clicking on that specific dataset. This issue affects Apache Superset version 1.5.2 and prior versions and version 2.0.0.

An authenticated attacker with write CSS template permissions can create a record with specific HTML tags that will not get properly escaped by the toast message displayed when a user deletes that specific CSS template record. This issue affects Apache Superset version 1.5.2 and prior versions and version 2.0.0.

Two legacy REST API endpoints for approval and request access are vulnerable to cross site request forgery. This issue affects Apache Superset version 1.5.2 and prior versions and version 2.0.0.

Upload data forms do not correctly render user input leading to possible XSS attack vectors that can be performed by authenticated users with database connection update permissions. This issue affects Apache Superset version 1.5.2 and prior versions and version 2.0.0.

Dashboard rendering does not sufficiently sanitize the content of markdown components leading to possible XSS attack vectors that can be performed by authenticated users with create dashboard permissions. This issue affects Apache Superset version 1.5.2 and prior versions and version 2.0.0.

A vulnerability in the SQL Alchemy connector of Apache Superset allows an authenticated user with read access to a specific database to add subqueries to the WHERE and HAVING fields referencing tables on the same database that the user should not have access to, despite the user having the feature flag "ALLOW_ADHOC_SUBQUERY" disabled (default value). This issue affects Apache Superset version 1.5.2 and prior versions and version 2.0.0.

Apache Superset up to 1.5.1 allowed for authenticated users to access metadata information related to datasets they have no permission on. This metadata included the dataset name, columns and metrics.
