The server retrieves API keys from environment variables, which is a good practice. It utilizes `child_process.execFile` with `curl` for external HTTP requests and file downloads. While `execFile` is generally safer than `exec`, direct user-controlled `outputPath` or `imageUrl` parameters could pose risks if not strictly validated against path traversal or malicious URLs by the underlying functions. The implementation uses `path.dirname` and `mkdirSync` to ensure output directories exist, which provides some mitigation against arbitrary file writes, but a comprehensive path validation against traversal is not explicitly evident in the provided snippets. Temporary files are created in `/tmp`, which is generally acceptable for transient data.
