@prosopo/procaptcha-bundle@4.4.1
AI Security Review
scanned 2mo ago · by lpm-firewall-aiSource inspection found a browser CAPTCHA bundle with no lifecycle scripts or malicious primitives. Environment settings and dynamic imports are limited to configuring and loading its declared CAPTCHA dependencies.
Static reason
One or more suspicious static signals were detected.
Trigger
A web page imports or loads the bundle and renders a CAPTCHA widget.
Impact
No package-originated credential theft, persistence, destructive action, install-time mutation, or direct exfiltration was found.
Mechanism
Widget initialization and CAPTCHA-provider prefetch.
AI rationale
Source inspection found a browser CAPTCHA bundle with no lifecycle scripts or malicious primitives. Environment settings and dynamic imports are limited to configuring and loading its declared CAPTCHA dependencies.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes a browser bundle and contains no install lifecycle hook.
- The built entry imports local modules and declared Prosopo CAPTCHA dependencies.
- Source config reads named CAPTCHA settings and passes them into a validated widget configuration.
- The widget mounts the declared CAPTCHA component; no direct credential harvesting, filesystem access, shell execution, or network primitive was found.
Evidence against
- Importing the browser entry performs widget initialization and may prefetch CAPTCHA detection after a caller supplies a site key.
- Environment-variable references configure the CAPTCHA service; they do not enumerate or exfiltrate the consumer environment.
- The scanner's runtime dependency bridge is consistent with declared dependencies and the bundle's widget role.

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