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 scanner’s credential exfiltration hint is not supported by the inspected source: the only outbound request is post-success product telemetry with a limited payload sent to the package’s own endpoint. The CLI manifest has no install hook, and the required dependency entry files expose ordinary prompt, styling, and command APIs. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-24T12:23:29.383Z - **Finished:** 2026-10-24T12:24:33.723Z - **Download time:** 510 ms - **Static scan time:** 1377 ms - **AI review time:** 62452 ms - **Total time:** 64340 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 sends limited product usage telemetry to the package’s own telemetry endpoint after successful scaffolding. - **Trigger:** A user runs the CLI and scaffolding completes successfully. - **Impact:** The inspected payload contains no credentials, host identifiers, or project name, and the recipient is package-aligned. - **Review source:** ai\_review - **Reviewed:** 2026-10-24T12:24:33.723Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI posts its version, platform, CI category, selected options, and explicit flags; environment settings can disable the report. - **Rationale:** The scanner’s credential exfiltration hint is not supported by the inspected source: the only outbound request is post-success product telemetry with a limited payload sent to the package’s own endpoint. The CLI manifest has no install hook, and the required dependency entry files expose ordinary prompt, styling, and command APIs. - **Files touched:** dist/index.js - **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 and development scripts; no install lifecycle hook is present., After successful scaffolding, the CLI sends version, platform, CI category, flags, and project selections to the package’s Newt telemetry endpoint., Telemetry can be disabled with environment settings, and the reviewed payload contains no credentials, host identifiers, or project name., The inspected @clack/prompts entry files expose prompt functionality., The inspected chalk entry files implement terminal styling., The inspected commander entry files expose command-line parsing APIs. ## Affected versions and remediation This report applies to create-newt-app@0.31.8. - Review the evidence and your use of create-newt-app@0.31.8 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.
