What is CVE-2025-1385?

The library bridge feature in ClickHouse can pose security risks when it is enabled. This feature exposes an HTTP API on localhost, allowing the clickhouse-server to load libraries from specified paths and execute them within isolated processes. If a server is misconfigured, attackers with access to certain table engines may exploit this to execute arbitrary code. It's crucial to inspect the configuration file to determine whether the library bridge is enabled, particularly by checking for the specific setting that exposes port 9019.
