Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The scanner's credential-exfiltration hint is not supported by the inspected payload or send path, and the manifest has no install hook. The selected ejs and execa dependencies are active but their implementations remain unreviewed, so the source does not support a clean verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-24T12:23:48.399Z - **Finished:** 2026-10-24T12:24:41.647Z - **Download time:** 253 ms - **Static scan time:** 1297 ms - **AI review time:** 51697 ms - **Total time:** 53248 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 confirmed in the inspected package source. Review remains unresolved because active ejs and execa dependencies lack inspected implementation source. - **Trigger:** Running the create-newt-app CLI triggers scaffolding and its selected template and shell-command dependencies. - **Impact:** The unavailable dependency behavior cannot be fully assessed; the observed telemetry discloses scaffold and environment categories, not credentials. - **Evidence paths:** package.json, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-24T12:24:41.647Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI renders templates with ejs and runs commands through execa; their implementations were unavailable in the inspected snapshot. A successful run also sends configuration metadata to the package's telemetry endpoint, subject to an opt-out check. - **Rationale:** The scanner's credential-exfiltration hint is not supported by the inspected payload or send path, and the manifest has no install hook. The selected ejs and execa dependencies are active but their implementations remain unreviewed, so the source does not support a clean verdict. - **Files touched:** package.json, dist/index.js - **Network endpoints:** https://newt-telemetry.newt-app.workers.dev ### Review decision - **Verdict:** Manual Review - **Confidence:** 72.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest exposes dist/index.js as a CLI and lists only build and development scripts, with no install lifecycle hook., After successful scaffolding, the CLI sends product configuration metadata to the Newt telemetry endpoint; the payload contains CLI and environment categories plus selected options, and the send path has an opt-out check., The active CLI imports ejs and execa and uses them for template rendering and shell commands. Their registry implementations are not present in the inspected snapshot, so this review cannot resolve their behavior. - **Evidence against:** The inspected telemetry payload contains no credential or project-file fields; it reports version, platform, CI provider, flags, and scaffold selections., The observed subprocess calls run pnpm or git as part of scaffolding, installation, formatting, and optional Git setup. ## Affected versions and remediation This report applies to create-newt-app@0.31.9. - Review the evidence and your use of create-newt-app@0.31.9 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.
