Pre-publish security scanner for browser extensions
AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms an install-time telemetry ping, but it is gated on existing explicit consent and sends only coarse metadata. Other sensitive operations are tied to named user commands, with no concrete malicious behavior found.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall only after prior recorded telemetry consent; otherwise explicit extenshi commands.
Impact
May create an anonymous telemetry ID and send coarse install metadata after opt-in; no credential harvesting, remote code execution, or broad control-surface mutation found.
Mechanism
consent-gated PostHog telemetry and user-invoked extension scanning/publishing
AI rationale

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- postinstall reads ~/.extenshi/config.json and can send an install telemetry event.
- The lifecycle script can create an anonymous ID in the same config file after consent.
Evidence against
- postinstall exits unless recorded telemetry is exactly true.
- Install telemetry is limited to package/version, runtime, OS/arch, and anonymous ID.
- CLI telemetry prompts on an interactive first run before emitting events.
- Networked scanning and publishing are explicit CLI commands; scan upload is user-invoked.
