## Security analysis

### Published attack-surface review

- **Summary:** Running \`emp web\` exposes an unauthenticated coding agent on all network interfaces. The server enables automatic approvals and can execute shell commands through the agent.

- **Trigger:** A user runs \`emp web\`, then a network client sends requests to the exposed web server.

- **Impact:** A reachable client may induce commands in the selected workspace and access their output through the agent.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-04T04:22:14.225Z

### AI review details

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

- **Mechanism:** Network-exposed agent with automatic approval and shell command execution.

- **Rationale:** The package does not show covert install-time theft or persistence, but its explicitly launched web mode has a concrete unauthenticated remote command-execution path. This is a critical vulnerability rather than sufficient evidence of malicious intent.

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

- **Network endpoints:** 0.0.0.0

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 94.0%

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

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Medium

- **Evidence for:** The web server enables automatic tool approval by default., The server listens on every network interface., A public streaming chat route passes request data into an agent turn., Trusted mode bypasses normal tool approval., The command tool runs supplied commands through a shell., The API also exposes a route that answers pending approvals.

- **Evidence against:** The risky server is started only by the explicit \`emp web\` command., The command tool still has path and destructive-command checks., The install hook exits unless EMP\_EXE\_URL is explicitly set.
