What is CVE-2026-23984?

An Improper Input Validation vulnerability in Apache Superset allows authenticated users with SQLLab access to circumvent read-only verification checks for PostgreSQL database connections. The system aims to prevent unauthorized DML operations like INSERT, UPDATE, and DELETE on read-only connections, but it fails to adequately filter specially crafted SQL statements. This oversight could lead to unintended database modifications, posing a risk to data integrity. It is crucial for users to upgrade to version 6.0.0, which resolves this vulnerability.
