CVE-2026-23984: Apache Superset

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Apache Superset: before 6.0.0 (fixed in 6.0.0)
