lucien-form-builder@2.8.45
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe package has no active install hook or harmful account, credential, or data-exfiltration behavior. Its entry point does automatically compute unused browser fingerprint signals, but the reviewed code shows no transmission, so this does not establish an attack.
Static reason
No blocking static signals were detected.
Trigger
Importing the package entry point in a browser.
Impact
Unnecessary browser probing may affect privacy expectations, but no fingerprint transmission or other harmful effect was identified.
Mechanism
index.js imports src/fingerprint for side effects, which runs a list of browser tests and stores their results in a module-local object. The public-IP test is registered but is not in the executed test list.
AI rationale
The package has no active install hook or harmful account, credential, or data-exfiltration behavior. Its entry point does automatically compute unused browser fingerprint signals, but the reviewed code shows no transmission, so this does not establish an attack.

Decision evidence
public snapshotAI called this Clean at 85.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest points to index.js and has an empty prepare script; it declares no install, preinstall, or postinstall hook.
- The entry point imports src/fingerprint as a side effect, and that module automatically gathers browser fingerprint signals into a private in-memory object.
- The public-IP probe is defined in src/fingerprint.js but is not included in the automatically executed browserTests list; no transmission of the gathered fingerprint was identified.
- The added .claude/settings.local.json only allows the command Bash(docker info *).
Evidence against
- Fingerprint collection runs automatically when the package entry point is imported, even though the form-builder entry point does not use or expose its result.
- The fingerprint module probes browser characteristics including audio, canvas, installed fonts, language, local IP, platform, plugins, screen, and WebGL.
