## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 15 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.46.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

No confirmed malicious attack surface. Process and loopback networking behavior is activated only by the connector's explicit runtime launch path.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 96.0%

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:** No confirmed malicious attack surface. Process and loopback networking behavior is activated only by the connector's explicit runtime launch path.

- **Trigger:** An application explicitly invokes the connector launch configuration.

- **Impact:** No unconsented install-time action or external data exfiltration was confirmed.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-13T10:38:42.634Z

### AI review details

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

- **Mechanism:** Starts and attaches to a password-protected local OpenCode server.

- **Rationale:** The scanner's reverse-shell match is a false positive: the code starts a local OpenCode server on loopback and attaches a client to it. Source inspection found no lifecycle hook or concrete malicious behavior.

### Review decision

- **Verdict:** Clean

- **Confidence:** 96.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason.

- **Evidence for AI clean decision:** The runtime shim starts an OpenCode child process and records its PID., The connector explicitly builds a launch command for that shim., The manifest contains build and test scripts but no install lifecycle hook.

- **Evidence against:** The child server binds only to 127.0.0.1 and uses a fresh random password., The apparent shell use is fixed-argument process inspection and OpenCode invocation, not a reverse shell., No source evidence shows credential harvesting, external exfiltration, dynamic payload loading, or automatic installation-time execution.

## Affected versions and remediation
