AI Security Review
scanned 7d ago · by lpm-firewall-aiThe inspected entry points and configuration support the package’s CAPTCHA rendering purpose, and the package declares no lifecycle scripts. The only identified telemetry is a 0.1% sampled beacon to Prosopo, gated on a provider-list setting and carrying the site host and key.
Static reason
One or more suspicious static signals were detected.
Trigger
Importing the browser entry initializes the widget API and calls boot; widget rendering follows the configured implicit or explicit mode.
Impact
Expected CAPTCHA rendering and limited usage telemetry; no credential theft, unrelated account action, or install-time behavior was found.
Mechanism
Reads CAPTCHA configuration and page elements, then creates widgets. A Prosopo usage beacon is sampled and guarded by a provider-list setting.
AI rationale
The inspected entry points and configuration support the package’s CAPTCHA rendering purpose, and the package declares no lifecycle scripts. The only identified telemetry is a 0.1% sampled beacon to Prosopo, gated on a provider-list setting and carrying the site host and key.

Decision evidence
public snapshotAI called this Clean at 92.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package exports browser-oriented ESM and CommonJS widget entry points and declares no lifecycle scripts.
- Startup renders CAPTCHA widgets from page elements when implicit rendering is configured; explicit rendering is also supported.
- Environment variables configure the site key and CAPTCHA environment/server settings.
- The usage beacon targets Prosopo, samples at 0.1%, and sends only when a provider-list override is present.
