CVE-2021-41971Network attack vector

Authenticated SQL injection via unescaped URL parameter

Published Oct 18, 2021 · Updated Aug 4, 2024

SQL injection in Apache Superset 1.3.0 and earlier allows remote authenticated users to execute arbitrary SQL via a crafted URL. With ENABLE_TEMPLATE_PROCESSING enabled, the url_param Jinja helper inserts an HTTP parameter into rendered SQL without escaping it. The feature is disabled by default, and exploitation requires a template that incorporates the attacker-controlled parameter; resulting access remains bounded by the connected database account's permissions.
