AI Security Review
scanned 19d ago · by lpm-firewall-aiSource inspection supports clean: the manifest has no install hook, and the runtime behavior is consistent with a CAPTCHA widget. The environment-variable matches configure the widget, while the example.com matches occur in test fixtures.
Static reason
One or more suspicious static signals were detected.
Trigger
Widget setup occurs when the page loads or an application calls the exported render API.
Impact
No attack impact was identified in the inspected source.
Mechanism
The entrypoint configures and mounts the Prosopo frictionless CAPTCHA; detector prefetch requires a site key and is skipped in manual mode.
AI rationale
Source inspection supports clean: the manifest has no install hook, and the runtime behavior is consistent with a CAPTCHA widget. The environment-variable matches configure the widget, while the example.com matches occur in test fixtures.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json identifies the Prosopo CAPTCHA repository and its package directory; its scripts are build and test commands, with no install lifecycle hook.
- The entrypoint exposes widget controls and gates detector prefetch on a site key and non-manual start mode.
- Environment variables are mapped into CAPTCHA configuration fields, and the widget mounts through the Prosopo frictionless package.
- Inspected distribution searches found no shell execution, eval, cookie access, or direct fetch implementation.

Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.
