@prosopo/procaptcha-bundle@4.4.5
AI Security Review
scanned 26d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook, and the inspected entry source implements package-aligned CAPTCHA rendering and conditional detector prefetch. The suspicious scanner hints are not supported by the inspected source as evidence of an attack.
Static reason
One or more suspicious static signals were detected.
Trigger
The browser imports the package and renders a procaptcha element with a site key; prefetch is skipped in manual start mode.
Impact
No malicious effect was established from the inspected source.
Mechanism
The entry loads widget utilities and, when enabled, dynamically imports Prosopo dependencies to prefetch a detector for the provided site key.
AI rationale
The manifest has no install lifecycle hook, and the inspected entry source implements package-aligned CAPTCHA rendering and conditional detector prefetch. The suspicious scanner hints are not supported by the inspected source as evidence of an attack.
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 identifies the package, points its module entry to dist/index.js, and marks it side-effect-free.
- The manifest lists build and test scripts but no install lifecycle hooks.
- The built entry imports the package's own widget utilities and declared Prosopo dependencies.
- Source prefetch runs only when a site key exists and start mode is not manual; it calls the Prosopo detector prefetch API.
- Source rendering targets page elements with the procaptcha class.
