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 and paywall telemetry to its own service during interactive use. The event data is limited and has opt-outs, 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:** 94.0% - **Started:** 2026-10-31T14:43:56.608Z - **Finished:** 2026-10-31T14:44:38.319Z - **Download time:** 764 ms - **Static scan time:** 79 ms - **AI review time:** 40867 ms - **Total time:** 41711 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 during interactive CLI and MCP use. - **Trigger:** Starting an interactive free CLI run, or attempting a paid operation without a valid license; telemetry can be disabled with DO\_NOT\_TRACK=1 or READYSTACK\_NO\_TELEMETRY, and is skipped in CI. - **Impact:** The vendor learns that the package was used and whether a license was missing or rejected; no project contents or credentials are included in these event payloads. - **Evidence paths:** cli.js, license.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T14:44:38.319Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI posts product usage and paywall events to the vendor endpoint. License validation and the rules feed also contact their documented service endpoints. - **Rationale:** The package sends undisclosed runtime usage and paywall telemetry to its own service during interactive use. The event data is limited and has opt-outs, so this warrants a warning rather than a malicious verdict. - **Files touched:** ~/.config/readystack/sv-rechengroessen-lint-2026.json (or READYSTACK\_HOME/sv-rechengroessen-lint-2026.json) - **Network endpoints:** getreadystack.com/api/ev, getreadystack.com/api/lic, getreadystack.com/api/rules/, 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:** Interactive free CLI runs send a usage event to getreadystack.com unless telemetry opt-outs or CI are detected., Missing or rejected license checks send a paywall event during interactive CLI or MCP use; its payload contains the product slug, source and reason., The README documents paid folder scans and licensing but does not disclose the usage events. - **Evidence against:** The usage event payload is limited to the product slug, source and usage reason; it does not include project files, credentials or identifying machine details., License keys are sent to the package's licensing service for validation, consistent with the documented paid features. ## Affected versions and remediation This report applies to @readystack/sv-rechengroessen-lint-2026@1.0.4. - Review the evidence and your use of @readystack/sv-rechengroessen-lint-2026@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.
