## Security analysis

### Published attack-surface review

- **Summary:** Running emp web starts an unauthenticated service on every network interface. A network client can register an MCP command that is saved and executed by the server.

- **Trigger:** The user runs emp web while the service is reachable from another network client.

- **Impact:** A remote client can execute commands as the user and leave an MCP configuration that will run again when reloaded.

- **Evidence paths:** emp-web/server.cjs, lib/mcp.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-04T04:44:25.742Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Unauthenticated MCP command registration followed by process spawning.

- **Rationale:** The source establishes a serious remotely reachable command-execution vulnerability, but it requires the explicit web command and does not show automatic malicious execution on ordinary install. The environment-gated binary downloader is also unsafe because the downloaded executable is later launched without verification.

- **Files touched:** emp-web/server.cjs, lib/mcp.js, .emp/mcp.json

- **Network endpoints:** 0.0.0.0

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 97.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Low

- **Evidence for:** The package runs a postinstall hook., That hook can download an executable from an environment-selected URL without integrity verification., The CLI launches that downloaded executable when present., The web server enables automatic approval, listens on all interfaces, and exposes an unauthenticated endpoint that accepts an MCP command., The MCP handler saves the supplied command and spawns it with the current process environment.

- **Evidence against:** The postinstall download exits unless EMP\_EXE\_URL is already set., The reviewed manifest has no dependency on another emp-code release., The web server is started only by the explicit emp web command.
