⚠ Under reviewAI Security Review
scanned 12d ago · by lpm-firewall-aiThe 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.
Static reason
High-risk behavior combination matched malicious policy.
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.
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.
AI 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.

Decision evidence
public snapshotAI called this Manual Review at 72.0% confidence as Unknown with medium false-positive risk.
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.
