DescriptionCVE.org
An Improper Input Validation vulnerability exists in Apache Superset that allows an authenticated user with SQLLab access to bypass the read-only verification check when using a PostgreSQL database connection. While the system effectively blocks standard Data Manipulation Language (DML) statements (e.g., INSERT, UPDATE, DELETE) on read-only connections, it fails to detect them in specially crafted SQL statements.
This issue affects Apache Superset: before 6.0.0.
Users are recommended to upgrade to version 6.0.0, which fixes the issue.
AnalysisAI
Authenticated users in Apache Superset versions before 6.0.0 can execute write operations against PostgreSQL databases configured as read-only by crafting specially formatted SQL statements that evade validation checks. This allows an attacker with SQLLab access to perform unauthorized data modifications despite read-only protections being in place. No patch is currently available for affected versions.
Technical ContextAI
