AI Security Review
scanned 13d ago · by lpm-firewall-aiThe postinstall hook requires previously recorded affirmative telemetry consent before creating an ID or sending an install event. Other flagged execution behavior is tied to explicit CLI workflows, and the inspected dependency snapshots contain no install hooks.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm runs the postinstall hook; it exits without sending unless telemetry is already true in the Extenshi configuration.
Impact
The inspected behavior supports opted-in adoption telemetry; it does not send credentials, artifact contents, or user paths.
Mechanism
With consent, the hook posts an install event, anonymous ID, package and runtime versions, and coarse platform details to the default PostHog host.
AI rationale
The postinstall hook requires previously recorded affirmative telemetry consent before creating an ID or sending an install event. Other flagged execution behavior is tied to explicit CLI workflows, and the inspected dependency snapshots contain no install hooks.

Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json runs scripts/postinstall.cjs, which exits unless saved telemetry consent is true; after that gate it sends an install event with an anonymous ID and coarse runtime metadata to the default PostHog host.
- The inspected @extenshi/contracts, @extenshi/publisher, and @resvg/resvg-wasm dependency snapshots show ordinary library entrypoints and no install lifecycle hooks.
- The CLI scan and evidence-ingest flows submit user-selected artifacts to Extenshi service endpoints as part of explicit commands.
- The screenshot loader resolves Playwright packages for the screenshot feature; the browser opener launches a platform URL handler, and shell commands in amo-source run in a temporary clean room for verification.
- The report feedback request is initiated by a user click, and smoke code records browser errors for extension contexts.
Evidence against
- The install hook does send telemetry automatically after consent has previously been saved, but source requires telemetry: true before creating an anonymous ID or making the request.
- Scanner flags for dynamic loading and child-process or shell use resolve to screenshot support, browser opening, and explicitly invoked clean-room rebuild behavior.
