## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 24 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 7.1.56
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

When the engine is started with an AI model, the model can invoke a shell-backed command tool. An enabled private WeChat tool also passes tool input into a shell command.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-09-16T09:47:28.576Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** When the engine is started with an AI model, the model can invoke a shell-backed command tool. An enabled private WeChat tool also passes tool input into a shell command.

- **Trigger:** Run engine7 start with a configuration that exposes these tools to an AI session.

- **Impact:** A prompt-influenced model could run commands with the engine user's permissions; the private tool's command construction increases injection risk.

- **Evidence paths:** dist/engine-startup.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-16T09:48:47.987Z

### AI review details

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

- **Mechanism:** AI-mediated shell command execution.

- **Rationale:** No install-time attack chain or confirmed fixed exfiltration endpoint was found, so blocking as malware is not supported. The reachable shell execution features nevertheless warrant a warning for an AI-agent runtime.

- **Files touched:** dist/engine-startup.mjs

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The runtime registers an AI-facing exec tool that runs supplied commands through a shell., A private WeChat query tool builds a shell command from tool input and invokes it, while referring to a hard-coded developer-machine script path., This is a large agent runtime that can act on configured model and channel inputs; its command capability is a material dual-use risk.

- **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The command and persistence features are reached through explicit CLI or runtime use, not package installation., No fixed credential-exfiltration gateway or hidden network endpoint was found in the inspected entrypoints.

## Affected versions and remediation

This report applies to engine7@7.1.56.

- Review the evidence and your use of engine7@7.1.56 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
