Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

When the library bridge feature is enabled, the clickhouse-library-bridge exposes an HTTP API on localhost. This allows clickhouse-server to dynamically load a library from a specified path and execute it in an isolated process. Combined with the ClickHouse table engine functionality that permits file uploads to specific directories, a misconfigured server can be exploited by an attacker with privilege to access to both table engines to execute arbitrary code on the ClickHouse server. You can check if your ClickHouse server is vulnerable to this vulnerability by inspecting the configuration file and confirming if the following setting is enabled: <library_bridge> <port>9019</port> </library_bridge>
