Treat them as untrusted evidence. 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 source sends runtime usage telemetry to the publisher’s host, but does not disclose it in the README. Its payloads contain only package and event metadata, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-31T13:41:13.348Z - **Finished:** 2026-10-31T13:41:47.069Z - **Download time:** 766 ms - **Static scan time:** 57 ms - **AI review time:** 32897 ms - **Total time:** 33721 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 usage telemetry is sent to the package publisher’s host. - **Trigger:** After a free CLI scan, or when a license check fails; telemetry is limited to interactive or MCP sessions unless opted out. - **Impact:** The publisher can track package usage and paywall events; no sensitive user or project data was identified in the event payloads. - **Evidence paths:** cli.js, license.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T13:41:47.069Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** HTTPS POST events report the package slug, invocation source and a reason such as free, no\_key or invalid. - **Rationale:** The source sends runtime usage telemetry to the publisher’s host, but does not disclose it in the README. Its payloads contain only package and event metadata, so this warrants a warning rather than a block. - **Files touched:** cli.js, license.js - **Network endpoints:** https://getreadystack.com/api/ev ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** A free CLI run sends a usage event to getreadystack.com containing the package slug, CLI source and a fixed reason., The usage ping runs after free scans; telemetry is disabled by opt-out environment variables, but the README does not disclose it., License or paywall events send only the package slug, source and reason to the same host. - **Evidence against:** The reported events do not include file contents, credentials, hostnames or other identifying details., The package is a CLI audit tool, and its license checks and rule feed serve its paid scanning features., The network pings are limited to interactive or MCP use and can be disabled with DO\_NOT\_TRACK=1 or READYSTACK\_NO\_TELEMETRY. ## Affected versions and remediation This report applies to @readystack/view-in-browser-leak-audit@1.0.2. - Review the evidence and your use of @readystack/view-in-browser-leak-audit@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.
