CVE-2023-42502Network attack vector

Authenticated redirection via Host-trusted dataset links

Published Nov 28, 2023 · Updated Aug 2, 2024

Open redirect in Apache Superset before 3.0.0 allows remote authenticated users to redirect dataset viewers through a crafted Host header. Dataset explore_url handling compares absolute links with the request host instead of forcing them to remain relative, so a spoofed Host value makes an external link appear same-origin. Dataset-update permission is required, and a viewer must click the altered link; navigation reaches the external site without directly modifying Superset data.
