LiteLLM 1.18.10 contains a remote code execution vulnerability in its MCP server creation functionality.

LiteLLM executes these values on the host without validation, enabling attackers to run arbitrary operating system commands. Successful exploitation may result in remote code execution with the privileges of the LiteLLM process.
