Pre-publish security scanner for browser extensions
AI Security Review
scanned 26d ago · by lpm-firewall-aiThe flagged install hook is affirmative-consent-gated telemetry, and the flagged runtime files support explicit scanner, login, and browser-testing workflows. The inspected source does not establish a concrete attack surface, so the package is clean.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Package installation with telemetry already enabled, or a user invoking the related CLI command.
Impact
The inspected behavior does not establish credential theft, unconsented broad system changes, or remote code execution.
Mechanism
The postinstall hook sends installation metadata to the configured telemetry host; separate CLI helpers use loopback networking and a temporary Firefox profile for login and smoke testing.
AI rationale
The flagged install hook is affirmative-consent-gated telemetry, and the flagged runtime files support explicit scanner, login, and browser-testing workflows. The inspected source does not establish a concrete attack surface, so the package is clean.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest defines a postinstall telemetry hook and exposes dist/cli.js as the command-line entrypoint.
- The install hook exits unless telemetry consent is already recorded; it sends installation metadata to PostHog.
- Firefox smoke testing is an explicit CLI subcommand and creates a disposable local profile.
- The login helper serves its callback on loopback; the inspected source shows no package-controlled remote execution or credential harvesting.
