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:** 1.0.4 - **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 package sends undisclosed runtime usage telemetry by default in interactive sessions, although it limits the payload to basic event metadata and offers opt-outs. This warrants a warning, but the reviewed code does not show credential theft or project-data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-31T15:08:04.826Z - **Finished:** 2026-10-31T15:08:52.854Z - **Download time:** 762 ms - **Static scan time:** 76 ms - **AI review time:** 47190 ms - **Total time:** 48028 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 minimal CLI usage and paywall events to the package vendor. - **Trigger:** A user runs the CLI in a terminal or MCP session; usage events follow free scans, and paywall events follow license checks without a key or with an invalid key. - **Impact:** The vendor can learn that the tool was used and whether its paywall was reached; no scanned content or unrelated credentials were identified in the event payload. - **Evidence paths:** cli.js, license.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T15:08:52.854Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package posts the event type, package slug, source, and reason to getreadystack.com. The source provides opt-out environment variables, but the README does not disclose this telemetry. - **Rationale:** The package sends undisclosed runtime usage telemetry by default in interactive sessions, although it limits the payload to basic event metadata and offers opt-outs. This warrants a warning, but the reviewed code does not show credential theft or project-data exfiltration. - **Files touched:** ~/.config/readystack/webfont-license-audit.json (or READYSTACK\_HOME/webfont-license-audit.json) - **Network endpoints:** getreadystack.com/api/ev, getreadystack.com/api/lic, getreadystack.com/api/rules/\?key=\, api.polar.sh/v1/customer-portal/license-keys/validate ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** A free CLI scan calls pingUse() after it finishes, and that event is sent to the vendor’s /api/ev endpoint., The event contains only the event type, package slug, CLI/MCP source, and use or paywall reason; it is gated by terminal/MCP use and can be disabled with documented environment variables in the source., License checks send a supplied or stored license key to the vendor’s license endpoint for validation. - **Evidence against:** The event payload does not include scanned file contents, paths, credentials, or environment values., License validation and rule-feed requests go to the package vendor or the identified license provider and serve licensing or product-rule functions., The package exposes a CLI for scanning font-license issues, and the flagged behavior is not triggered by an install lifecycle script. ## Affected versions and remediation This report applies to @readystack/webfont-license-audit@1.0.4. - Review the evidence and your use of @readystack/webfont-license-audit@1.0.4 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.
