Treat them as untrusted evidence. 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:** 0.31.6 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The flagged entrypoint sends package-aligned, limited usage telemetry after a user-invoked scaffold, with an on-screen notice and opt-out controls. Inspected source does not support credential exfiltration or other attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-24T12:23:20.395Z - **Finished:** 2026-10-24T12:24:46.404Z - **Download time:** 513 ms - **Static scan time:** 1313 ms - **AI review time:** 84182 ms - **Total time:** 86009 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 attack was identified. The CLI reports limited scaffold usage metadata to its package telemetry endpoint. - **Trigger:** A user runs the CLI and scaffolding completes successfully. - **Impact:** No credential, project path, project name, or file content transfer was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-24T12:24:46.404Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends one event containing version, platform, CI category, and selected scaffold options; it displays a notice and provides opt-out variables. - **Rationale:** The flagged entrypoint sends package-aligned, limited usage telemetry after a user-invoked scaffold, with an on-screen notice and opt-out controls. Inspected source does not support credential exfiltration or other attack behavior. - **Network endpoints:** https://newt-telemetry.newt-app.workers.dev ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes dist/index.js as the CLI and lists only build, development, test, and typecheck scripts; it has no install lifecycle hook., The reviewed dependency entrypoints serve prompts, terminal styling, and command-line parsing., The telemetry payload contains CLI and Node versions, platform, CI category, interaction mode, and scaffold selections; it does not include project names, paths, file contents, or credentials., After a successful scaffold, the CLI sends one event to the package’s telemetry endpoint. It displays a notice and supports environment-variable opt-outs. - **Evidence against:** Telemetry is enabled by default unless an opt-out variable is set. ## Affected versions and remediation This report applies to create-newt-app@0.31.6. - Review the evidence and your use of create-newt-app@0.31.6 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.
