Background
Apache Superset is an open-source data visualization and business intelligence tool that allows users to explore and visualize data through a web interface. It provides features such as dashboards, charts, and data exploration capabilities, making it a popular choice for organizations looking to derive insights from their data. However, a vulnerability has been identified that allows authenticated users to access sensitive information without proper permissions, raising concerns about data security.
Vulnerability Detail
A Sensitive Data Exposure vulnerability exists in Apache Superset that allows authenticated users to retrieve sensitive user information. Specifically, the Tag endpoint, which is disabled by default, can be exploited to access a list of objects associated with a specific tag. If these objects include Users, the API response improperly serializes and returns sensitive fields such as password hashes, email addresses, and login statistics. This vulnerability can be exploited by authenticated users with low privileges, such as those assigned the Gamma role, allowing them to view sensitive authentication data.
