@prosopo/procaptcha-bundle@4.4.6
AI Security Review
scanned 26d ago · by lpm-firewall-aiThe inspected behavior matches a browser CAPTCHA bundle: no lifecycle hook is declared, and detector prefetch is gated by site-key and start-mode checks. The environment reference and generated runtime import do not establish malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Loading the browser bundle or calling render with a site key; automatic prefetch is skipped in manual start mode.
Impact
No confirmed malicious effect or attack surface was established from the inspected behavior.
Mechanism
The bundle dynamically imports Prosopo detector modules and passes them the configured environment, IP mode, and site key.
AI rationale
The inspected behavior matches a browser CAPTCHA bundle: no lifecycle hook is declared, and detector prefetch is gated by site-key and start-mode checks. The environment reference and generated runtime import 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 identifies a browser-oriented module entrypoint and contains no install lifecycle hook.
- dist/index.js imports the package’s declared application modules and local widget utilities; the dependency bridge is ordinary bundler output.
- src/index.ts gates detector prefetch on a site key and skips it in manual mode.
- The prefetch passes the site key and IP preference to the Prosopo detector module; no unrelated credential or consumer-file access is shown.

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