CVE-2025-1385 — When the library bridge feature is enabled, the clickhouse-library-bridge exposes an HTTP API on localhost

High CVSS 7.5

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>

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
