## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 14 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.8.1
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The manifest and inspected entrypoint support the private monitoring purpose. Network destinations and credentials are supplied by the caller, and the suspicious VM and process-execution matches do not establish package-directed attack behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-20T07:54:35.478Z
- **Finished:** 2026-10-20T07:55:26.239Z

- **Total time:** 50761 ms

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:** No attack was identified. The bundle operates as a configured private API monitoring runner.

- **Trigger:** The CLI starts when invoked with APP\_URL and an AGENT\_TOKEN or RUNTIME\_TOKEN configured.

- **Impact:** No confirmed attack surface was established; the observed network and script behavior matches the package’s monitoring function and requires caller-supplied configuration.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-20T07:55:26.239Z

### AI review details

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

- **Mechanism:** It polls the configured service for monitor jobs, runs their requests and test scripts, and posts results back to that service.

- **Rationale:** The manifest and inspected entrypoint support the private monitoring purpose. Network destinations and credentials are supplied by the caller, and the suspicious VM and process-execution matches do not establish package-directed attack behavior.

- **Files touched:** package.json, dist/index.cjs

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest describes a private runner for monitoring internal and local APIs, and points its CLI and module entry to dist/index.cjs., The runner requires caller-provided APP\_URL and an AGENT\_TOKEN or RUNTIME\_TOKEN before polling begins., It polls for monitors and posts results to API paths under the configured APP\_URL, using the configured token., Monitor scripts are run in a VM sandbox with a timeout as part of the runner’s request-testing flow.

## Affected versions and remediation
