## 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:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 1.2.1
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The source indicates default-on runtime telemetry that includes machine context, while the README does not disclose it. This is a warning-level telemetry concern; the package’s expected chat and tool traffic and its telemetry opt-out weigh against a malicious verdict.

## Latest scan

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:** Undisclosed runtime telemetry sends diagnostic events and machine context to the package service by default.

- **Trigger:** Starting the CLI or its web server, unless telemetry is disabled in configuration or with NEXGEN\_DISABLE\_TELEMETRY.

- **Impact:** Unrequested diagnostic data about the runtime environment is transmitted to the vendor service. No credential or user prompt exfiltration was identified in the inspected telemetry path.

- **Evidence paths:** dist/main.mjs, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-10-30T09:04:53.549Z

### AI review details

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

- **Mechanism:** The bundled code initializes a telemetry appender that sends events with OS release, locale, terminal program, platform, architecture, Node version, CI status, and other event context to the Nexgen service.

- **Rationale:** The source indicates default-on runtime telemetry that includes machine context, while the README does not disclose it. This is a warning-level telemetry concern; the package’s expected chat and tool traffic and its telemetry opt-out weigh against a malicious verdict.

- **Files touched:** ~/.nexgenk/telemetry

- **Network endpoints:** https://ia.nexgen.systems

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 84.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The package exposes dist/main.mjs as its CLI entry point., The CLI enables telemetry unless config.telemetry is explicitly false; a separate environment variable can disable it., Telemetry context includes OS release, locale, terminal program, platform, architecture, Node version, and CI status, and sends events to https://ia.nexgen.systems., The README documents the agent’s chat and tool endpoints but does not disclose telemetry.

- **Evidence against:** The package is a terminal AI coding agent, so its documented chat and tool network requests fit its purpose., Telemetry string sanitization redacts URLs, common credentials, email addresses, and local file paths., Telemetry can be disabled through the telemetry config setting or NEXGEN\_DISABLE\_TELEMETRY.

## Affected versions and remediation
