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 finding is not supported by the inspected source: the reachable telemetry request sends project configuration choices and basic runtime data, not secrets or credentials. The request is package-aligned CLI usage telemetry with an opt-out, and the reviewed entrypoint and dependency sources establish no concrete attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-24T12:24:46.291Z - **Finished:** 2026-10-24T12:25:24.908Z - **Download time:** 255 ms - **Static scan time:** 1135 ms - **AI review time:** 37226 ms - **Total time:** 38617 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 in the reviewed source. The CLI sends limited usage telemetry after completing project creation. - **Trigger:** A user runs the CLI and the project creation completes successfully. - **Impact:** The endpoint receives usage and runtime information; no credential exposure or other concrete attack effect was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-24T12:25:24.908Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI posts selected template options and basic CLI/runtime details to the package's telemetry endpoint; environment values and credentials are not included in the payload. - **Rationale:** The scanner's credential finding is not supported by the inspected source: the reachable telemetry request sends project configuration choices and basic runtime data, not secrets or credentials. The request is package-aligned CLI usage telemetry with an opt-out, and the reviewed entrypoint and dependency sources establish no concrete attack behavior. - **Network endpoints:** https://newt-telemetry.newt-app.workers.dev ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes dist/index.js as a CLI and declares no lifecycle hooks., dist/index.js sends telemetry only after successful project creation; the event includes CLI and runtime details plus selected template options, with an opt-out., The telemetry code does not collect project names, environment values, or credentials; the reviewed @clack/prompts, chalk, and commander entry files are prompt, styling, and CLI library code., The dependency manifests and entry files reviewed for @clack/prompts, chalk, and commander show no lifecycle scripts. - **Evidence against:** dist/index.js sends usage telemetry by default to newt-telemetry.newt-app.workers.dev unless the user opts out. ## Affected versions and remediation This report applies to create-newt-app@0.33.3. - Review the evidence and your use of create-newt-app@0.33.3 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.
