Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.1.9 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found no lifecycle hooks or concrete malicious behavior. Network activity is tied to licensing, optional rule retrieval, and limited usage events; the observed license key transfer is to the package's licensing service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-24T17:43:35.981Z - **Finished:** 2026-10-24T17:44:33.502Z - **Download time:** 757 ms - **Static scan time:** 72 ms - **AI review time:** 56691 ms - **Total time:** 57521 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:** No malicious attack surface was identified. The package scans local files and uses network requests for license validation, optional rules, and limited usage events. - **Trigger:** Running the CLI activates its scan; paid features may validate a supplied or stored license, and an interactive free run may send a usage event. - **Impact:** No confirmed attack behavior was found. The inspected source does not establish arbitrary execution, persistence, destructive actions, or consumer policy changes. - **Review source:** ai\_review - **Reviewed:** 2026-10-24T17:44:33.502Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** License keys go to license validation endpoints. Usage events send product and event labels; no credential or file-content transfer was identified in those events. - **Rationale:** Source inspection found no lifecycle hooks or concrete malicious behavior. Network activity is tied to licensing, optional rule retrieval, and limited usage events; the observed license key transfer is to the package's licensing service. - **Files touched:** package.json, cli.js, license.js - **Network endpoints:** https://getreadystack.com/api/lic, https://api.polar.sh/v1/customer-portal/license-keys/validate, https://getreadystack.com/api/rules/, https://getreadystack.com/api/ev ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes cli.js as the executable and contains no lifecycle script., The CLI scans supplied text with configured rules; it does not execute the matched content., License keys are sent to the package's licensing service and Polar's license validation endpoint., Usage events contain a tool label and use reason; the CLI gates its event on an interactive terminal, while license events also honor CI and telemetry opt-outs., The CLI loads optional rule data through the license helper; inspection found no payload execution path. ## Affected versions and remediation This report applies to @readystack/cron-schedule-lint@0.1.9. - Review the evidence and your use of @readystack/cron-schedule-lint@0.1.9 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.
