CVE-2024-45537Network attack vector

Authenticated data exposure via JDBC property allowlist bypass

Published Sep 17, 2024 · Updated Mar 14, 2025

Improper input validation in Apache Druid 30.0.0 and earlier allows remote authenticated users to read protected data via crafted MySQL JDBC URLs. The external-database JDBC validator accepts properties embedded in a specially structured MySQL connection string without enforcing the configured allowed-properties list. Exploitation requires permission to create JDBC lookups or ingestion tasks and exposes data reachable through the resulting database connection.
