@prosopo/procaptcha-bundle@4.4.0
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe static hint reflects a transparent runtime dependency bridge and environment configuration, not an attack. The manifest has no install lifecycle hook and the inspected source implements browser captcha rendering only.
Static reason
One or more suspicious static signals were detected.
Trigger
A webpage imports the bundle and renders or implicitly loads a Procaptcha widget.
Impact
Expected captcha-provider communication may occur; no package-side filesystem, process, persistence, or credential-exfiltration behavior was found.
Mechanism
Dynamic loading of declared captcha modules for detector prefetch.
AI rationale
The static hint reflects a transparent runtime dependency bridge and environment configuration, not an attack. The manifest has no install lifecycle hook and the inspected source implements browser captcha rendering only.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The browser entry dynamically loads Prosopo captcha modules and calls detector prefetch with the configured environment and site key.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The inspected source is a React captcha widget wrapper; it contains no filesystem access, shell execution, credential harvesting, or direct exfiltration.
- The runtime call is gated by a site key and skipped for manual start mode.

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