@prosopo/procaptcha-bundle@4.5.6
AI Security Review
scanned 26d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook, and the inspected entrypoint and source show package-aligned captcha functionality. The flagged runtime shim is a short module import, while detector prefetch is gated by site key and start mode.
Static reason
One or more suspicious static signals were detected.
Trigger
Importing the bundle initializes its widget code; detector prefetch requires a site key and is skipped in manual start mode.
Impact
No credential collection, unrelated endpoint communication, install-time mutation, or other attack behavior was established.
Mechanism
The bundle imports local widget modules and Prosopo packages, then passes the configured site key and network mode to the Prosopo detector prefetch function.
AI rationale
The manifest has no install lifecycle hook, and the inspected entrypoint and source show package-aligned captcha functionality. The flagged runtime shim is a short module import, while detector prefetch is gated by site key and start mode.
Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json identifies the Prosopo captcha bundle and points its entrypoint to dist/index.js.
- The manifest has build and test scripts but no install lifecycle hook.
- dist/index.js imports local widget modules and Prosopo packages; its runtime shim only imports node:module.
- src/index.ts prefetches the detector only when a site key is present and start mode is not manual.
Evidence against
- Static hints flagged an apparent runtime dependency bridge, but the inspected bundle imports normal package and local modules.

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