## 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:** 1.0.3
- **Selected version is latest:** Yes
- **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 CLI sends undisclosed runtime telemetry to the package vendor during free use and license checks. The payloads are limited and opt-out controls exist, so this warrants a warning rather than a malicious verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-31T23:15:30.199Z
- **Finished:** 2026-10-31T23:16:03.376Z
- **Download time:** 1030 ms
- **Static scan time:** 64 ms
- **AI review time:** 32082 ms
- **Total time:** 33177 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:** Undisclosed runtime telemetry reports free CLI usage and license-gate events to the package vendor.

- **Trigger:** A free CLI scan or a missing/invalid license in an interactive CLI or MCP session.

- **Impact:** The vendor can count usage and license-gate events; the observed telemetry does not include identifying or project data.

- **Evidence paths:** cli.js, license.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-31T23:16:03.376Z

### AI review details

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

- **Mechanism:** POST requests send event type, product slug, source, and reason to getreadystack.com.

- **Rationale:** The CLI sends undisclosed runtime telemetry to the package vendor during free use and license checks. The payloads are limited and opt-out controls exist, so this warrants a warning rather than a malicious verdict.

- **Network endpoints:** getreadystack.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** A free CLI run automatically sends a usage event containing only the event type, product slug, source, and mode to getreadystack.com., The usage ping runs after free CLI scans; paywall events are also sent for missing or invalid licenses., The telemetry paths support opt-outs and avoid CI runs.

- **Evidence against:** The observed telemetry payloads contain no hostnames, usernames, paths, credentials, or file contents., License keys are sent to the package vendor or Polar for license validation.

## Affected versions and remediation

- Review the evidence and your use of @readystack/energielabel-feed-lint-eu@1.0.3 before allowing it. Restrict the permissions described in this report.
