Improper payload validation and an improper REST API response type, made it possible for an authenticated malicious actor to store malicious code into Chart's metadata, this code could get executed if a user specifically accesses a specific deprecated API endpoint. This issue affects Apache Superset versions prior to 2.1.2.  Users are recommended to upgrade to version 2.1.2, which fixes this issue.

Unnecessary read permissions within the Gamma role would allow authenticated users to read configured CSS templates and annotations. This issue affects Apache Superset: before 2.1.2. Users should upgrade to version or above 2.1.2 and run `superset init` to reconstruct the Gamma role or remove `can_read` permission from the mentioned resources.

Improper authorization check and possible privilege escalation on Apache Superset up to but excluding 2.1.2. Using the default examples database connection that allows access to both the examples schema and Apache Superset's metadata database, an attacker using a specially crafted CTE SQL statement could change data on the metadata database. This weakness could result on tampering with the authentication/authorization data.

Apache Superset would allow for SQLite database connections to be incorrectly registered when an attacker uses alternative driver names like sqlite+pysqlite or by using database imports. This could allow for unexpected file creation on Superset webservers. Additionally, if Apache Superset is using a SQLite database for its metadata (not advised for production use) it could result in more severe vulnerabilities related to confidentiality and integrity. This vulnerability exists in Apache Superset versions up to and including 2.1.0.

If an attacker gains write access to the Apache Superset metadata database, they could persist a specifically crafted Python object that may lead to remote code execution on Superset's web backend. The Superset metadata db is an 'internal' component that is typically only accessible directly by the system administrator and the superset process itself. Gaining access to that database should be difficult and require significant privileges. This vulnerability impacts Apache Superset versions 1.5.0 up to and including 2.1.0. Users are recommended to upgrade to version 2.1.1 or later.

An Incorrect authorisation check in SQLLab in Apache Superset versions up to and including 2.1.0. This vulnerability allows an authenticated user to query tables that they do not have proper access to within Superset. The vulnerability can be exploited by leveraging a SQL parsing vulnerability.

By default, stack traces for errors were enabled, which resulted in the exposure of internal traces on REST API endpoints to users. This vulnerability exists in Apache Superset versions up to and including 2.1.0.

Improper REST API permission in Apache Superset up to and including 2.1.0 allows for an authenticated Gamma users to test network connections, possible SSRF.

An improper default REST API permission for Gamma users in Apache Superset up to and including 2.1.0 allows for an authenticated Gamma user to test database connections.

A non Admin authenticated user could incorrectly create resources using the import charts feature, on Apache Superset up to and including 2.1.0.
