AI Security Review
scanned 12d ago · by lpm-firewall-aiThe install-time request is gated by a previously saved affirmative telemetry preference and reports limited package/runtime metadata. Reviewed runtime and dependency entrypoints did not establish a separate concrete attack surface.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installation, only when an existing Extenshi configuration records telemetry as enabled.
Impact
The permitted request reports package version and coarse Node, operating system, and architecture details with an anonymous identifier.
Mechanism
The hook reads the saved preference and posts an install event to the configured telemetry collector; CI and explicit opt-outs stop the request.
AI rationale
The install-time request is gated by a previously saved affirmative telemetry preference and reports limited package/runtime metadata. Reviewed runtime and dependency entrypoints did not establish a separate concrete attack surface.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json runs scripts/postinstall.cjs during installation, and the hook sends an install event only when ~/.extenshi/config.json already records telemetry: true; it skips CI and explicit opt-outs and sends package and coarse runtime metadata to the configured telemetry collector.
- The inspected CLI, smoke, login, source-archive, and rendering paths, plus the three prepared dependency entrypoints, show product functionality or library exports; no concrete attack behavior was identified in the reviewed source.
Evidence against
- The postinstall hook makes an outbound request and permits an environment variable to override the collector host, but the request is gated on a previously recorded affirmative telemetry preference.
