Pre-publish security scanner for browser extensions
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe postinstall telemetry is gated on explicit recorded consent and sends limited package/runtime metadata with an anonymous ID. The flagged network and process behavior is consistent with the CLI's project API, analytics setup, and local build-map features.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The install ping requires a dependency install and prior telemetry consent; project API calls, analytics setup, and build-map startup require invoking their respective CLI commands.
Impact
The install event shares package and runtime metadata with PostHog after consent. No automatic collection or transmission of unrelated credentials, files, or project data was identified.
Mechanism
The hook posts an anonymous install event to the configured PostHog host. Project requests use the API key with the configured BFF; analytics setup and local map-server execution are command-driven.
AI rationale
The postinstall telemetry is gated on explicit recorded consent and sends limited package/runtime metadata with an anonymous ID. The flagged network and process behavior is consistent with the CLI's project API, analytics setup, and local build-map features.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook sends its ping only when ~/.extenshi/config.json records telemetry: true; absent or declined consent exits without a request.
- The install ping reports package surface and version, Node version, OS and architecture, and an anonymous install ID.
- The default telemetry host is PostHog; the request posts an analytics event to the configured host.
- The CLI is a pre-publish security scanner with explicit commands for project setup and build-map operations.
Evidence against
- package.json defines a postinstall hook, so the consent-gated telemetry code runs during dependency installation.
- The CLI sends its API key as a bearer token to the configured Extenshi BFF when making project API requests.
- Some user-invoked features spawn a local build-map server or run a package-manager install command in the target project.
