CVE-2023-42505Network attack vector

Database connection username disclosure

Published Nov 28, 2023 · Updated Feb 13, 2025

Information disclosure in Apache Superset before 3.0.0 allows remote authenticated users to read database connection usernames. The Apache advisory identifies database-connection metadata as the disclosure locus but does not publish the code path or failed authorization operation. Access requires permission to read database-connection metadata, and the documented consequence is limited to sensitive connection details such as usernames.
