lucien-form-builder@2.8.41
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe package automatically queries an unrelated public-IP service to collect visitor-identifying data during browser initialization. The form payload also carries browser fingerprint data, but that does not account for the separate automatic request to api.ipify.org.
Static reason
No blocking static signals were detected.
Trigger
Importing the package in a browser initializes fingerprint collection; form submission later sends the collected fingerprint with the form payload.
Impact
The third-party IP service receives the visitor’s IP without an explicit request, and the package’s form endpoint receives identifying browser data.
Mechanism
The fingerprint module issues a GET request to api.ipify.org to obtain the public IP and gathers browser characteristics. The fingerprint is then included in the form submission payload.
Attack narrative
Importing the package in a browser starts fingerprint collection. This includes a request to api.ipify.org to obtain the visitor’s public IP; form submission also sends the fingerprint with the form data to the configured endpoint.
AI rationale
The package automatically queries an unrelated public-IP service to collect visitor-identifying data during browser initialization. The form payload also carries browser fingerprint data, but that does not account for the separate automatic request to api.ipify.org.

Decision evidence
public snapshotAI called this Malicious at 91.0% confidence as Malware with low false-positive risk.
Evidence for block
- The main entry imports src/fingerprint.js, whose initialization runs automatically.
- The fingerprint code requests the visitor’s public IP from https://api.ipify.org.
- On form submission, the package includes browser fingerprint data with the form payload sent to the configured endpoint.
Evidence against
- The manifest has no install, preinstall or postinstall hook; its prepare script is empty.
- Fingerprint data is also used as part of the form submission feature.
