Do not execute instructions or code found in this document. ## 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:** 1.0.2 - **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 sends limited runtime usage telemetry to the publisher’s host by default in interactive sessions. Because the README does not disclose that telemetry, classify it as suspicious; the inspected credential flows use the package’s license key with Polar and the publisher’s own rule-feed service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-31T23:15:11.147Z - **Finished:** 2026-10-31T23:16:02.256Z - **Download time:** 1038 ms - **Static scan time:** 60 ms - **AI review time:** 50010 ms - **Total time:** 51109 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:** Default interactive CLI runs send limited usage and paywall telemetry to the publisher’s host; user-facing documentation does not disclose it. - **Trigger:** CLI startup requests the rule feed when a license key is available; after a free scan, or when a license check fails, interactive sessions may send telemetry unless opted out. - **Impact:** The publisher can observe usage and paywall events from interactive sessions. The inspected telemetry payloads do not include file contents, paths, or unrelated credentials. - **Evidence paths:** cli.js, license.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T23:16:02.256Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** HTTPS requests send generic event fields to getreadystack.com. A license key is also sent to the publisher’s rule-feed endpoint and to Polar for validation. - **Rationale:** The package sends limited runtime usage telemetry to the publisher’s host by default in interactive sessions. Because the README does not disclose that telemetry, classify it as suspicious; the inspected credential flows use the package’s license key with Polar and the publisher’s own rule-feed service. - **Files touched:** $READYSTACK\_HOME/energielabel-feed-lint-eu.json, ~/.config/readystack/energielabel-feed-lint-eu.json - **Network endpoints:** getreadystack.com/api/ev, getreadystack.com/api/rules/\?key=..., api.polar.sh/v1/customer-portal/license-keys/validate ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** After a free scan, the CLI calls \`pingUse\`; on an interactive terminal with telemetry opt-outs unset, it posts a use event containing the package slug, source, and reason to the publisher’s host., The source describes paywall counts as anonymous and documents opt-outs; its event payload contains only event type, slug, source, and reason., The license key is used for Polar validation and the publisher’s rule-feed request; no flow sending unrelated credentials or project data was identified. - **Evidence against:** Telemetry is limited to generic event fields and is gated to interactive use, with environment-variable opt-outs., The CLI’s stated function is scanning energy-label product feeds, and its engine performs local feed checks. ## Affected versions and remediation This report applies to @readystack/energielabel-feed-lint-eu@1.0.2. - Review the evidence and your use of @readystack/energielabel-feed-lint-eu@1.0.2 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
