AI Security Review
scanned 26d ago · by lpm-firewall-aiSource inspection shows browser widget initialization and conditional loading of package-aligned Prosopo dependencies. The flagged runtime import is a local bundler runtime module, and no concrete attack behavior was found.
Static reason
One or more suspicious static signals were detected.
Trigger
Importing the published entrypoint initializes the browser widget; prefetch begins when a site key is present and start mode is not manual.
Impact
No malicious effect or confirmed attack surface was established.
Mechanism
The source loads Prosopo dependencies and exposes widget methods on the browser window.
AI rationale
Source inspection shows browser widget initialization and conditional loading of package-aligned Prosopo dependencies. The flagged runtime import is a local bundler runtime module, and no concrete attack behavior was found.
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 points to dist/index.js and defines package exports; its scripts are build and test commands, with no install lifecycle hook.
- The published entrypoint imports a local bundler runtime module and package utilities; no attacker-controlled dependency bridge or remote loader is shown in the excerpt.
- Detector prefetch requires a site key, skips manual mode, and dynamically imports the package’s Prosopo dependencies.
- The source installs the documented captcha widget API on window and dispatches a readiness event.

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