## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 0.6.4
- **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.

The package has no lifecycle execution, but its active runner forwards potentially sensitive monitored traffic to an unrestricted operator-configured endpoint. This warrants a warning for conditional credential exposure.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 90.0%

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 command is run, it can forward monitored API request and response content to an operator-configured service URL. No unconsented install-time attack was identified.

- **Trigger:** A user runs the command with APP\_URL and an agent or runtime token configured.

- **Impact:** Sensitive API content or authentication headers could be exposed if APP\_URL is configured to an untrusted destination.

- **Evidence paths:** dist/index.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-28T09:42:23.629Z

### AI review details

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

- **Mechanism:** The runner captures up to 16 KiB of request and response bodies plus headers, and posts those fields to APP\_URL.

- **Rationale:** The package has no lifecycle execution, but its active runner forwards potentially sensitive monitored traffic to an unrestricted operator-configured endpoint. This warrants a warning for conditional credential exposure.

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The manifest exposes a command-line entrypoint and contains no lifecycle hook., The runtime takes its service URL and authentication token from environment variables., The runner collects request and response headers and bodies, then includes them in posted results., No destination allowlist binds the configured service URL to the monitored API destination.

- **Evidence against:** No fixed external host, install hook, filesystem harvesting, or destructive action was identified.
