## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Unknown
- **Selected version:** 2.8.43
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The package silently runs browser fingerprint tests on import, an unexplained privacy-sensitive behavior for a form builder. I found no evidence that the collected values are transmitted, so this warrants a warning rather than a malicious verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 83.0%
- **Started:** 2026-11-03T14:36:43.270Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Importing the package automatically performs browser fingerprinting, an unexplained privacy-sensitive capability for a form-builder library.

- **Trigger:** Import of the package entry point in a browser.

- **Impact:** Browser and device characteristics are gathered without an explicit request; no transmission of the results was identified.

- **Evidence paths:** index.js, src/fingerprint.js

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T14:37:36.208Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The entry imports src/fingerprint.js, which runs browser tests and stores their results in a module-local object. A public-IP request helper is also defined but is not part of the automatic test list.

- **Rationale:** The package silently runs browser fingerprint tests on import, an unexplained privacy-sensitive behavior for a form builder. I found no evidence that the collected values are transmitted, so this warrants a warning rather than a malicious verdict.

- **Network endpoints:** https://api.ipify.org

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 83.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The main entry imports src/fingerprint.js as a side effect., That module automatically gathers browser characteristics, including installed fonts, local IP, canvas, platform and processor cores., A separate public-IP probe to api.ipify.org is defined in the fingerprint module, though it is absent from the automatic test list.

- **Evidence against:** The package declares an empty prepare script and no install or postinstall hook., The automatic fingerprint results are held in a module-local object; no transmission of those values was identified., The included WASM loader fetches blur\_bg.wasm relative to its own module URL.

path = rust_blur_lib/blur_bg.wasm
kind = wasm_module
sizeBytes = 16119
magicHex = [redacted]
```

### 8. Medium: Structural Risk Force Deep Review

### 10. Critical: Manifest Confusion
- **Category:** Manifest
- **Confidence:** 95.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/lucien-form-builder@2.8.43/package.json>)

Tarball package.json differs from the npm registry version manifest for scripts or dependency sets.

Public source snippet (untrusted):

```json
scripts changed=build
```

### 11. Medium: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 83.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/lucien-form-builder@2.8.43/index.js>)

The main entry imports src/fingerprint.js as a side effect.

Public source snippet (untrusted):

```javascript
import i18n from "./src/i18n";
import extendUnique from "./custom_rules/unique";
import extendPostalCode from "./custom_rules/postalcode";
import VeeValidate, { Validator } from "vee-validate";
import { version

- **Confidence:** 83.0%
- **Path:** src/fingerprint.js
- **Public source:** [View source](<https://unpkg.com/lucien-form-builder@2.8.43/src/fingerprint.js>)

That module automatically gathers browser characteristics, including installed fonts, local IP, canvas, platform and processor cores.

Public source snippet (untrusted):

```javascript
var browserTests = [
  "audio",

const fingerprint = {};

const init = async ()=> {
  for (let i = 0; i < browserTests.length; i++) {
    const test = browserTests[i];
    imprint.test([test]).th
