AI Security Review
scanned 26d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook, and the inspected entrypoint behavior supports rendering a captcha widget. The static environment-variable and runtime-bridge hints do not establish malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Importing the package entrypoint or rendering a widget with a site key.
Impact
No malicious effect was established from the inspected source.
Mechanism
The entrypoint loads widget utilities and conditionally prefetches the detector through the package's frictionless dependency.
AI rationale
The manifest has no install lifecycle hook, and the inspected entrypoint behavior supports rendering a captcha widget. The static environment-variable and runtime-bridge hints do not establish malicious behavior.
Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes the distribution bundle as the package entrypoint and defines build and test scripts, with no install lifecycle hook.
- dist/index.js imports widget utilities and starts detector prefetch for a supplied site key; the inspected code shows no independent attack behavior.
