## 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:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 2.8.40
- **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 automatically collects browser fingerprint attributes and includes them with form submissions, without clear disclosure in the reviewed code. This may support fraud prevention, but the extra identifying data collection presents a user privacy risk.

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:** Automatic browser fingerprint collection is included in submitted form data; the source does not establish whether this collection is disclosed to form users.

- **Trigger:** Importing the package in a browser starts fingerprint collection; submitting a form sends the collected values.

- **Impact:** This can transmit identifying browser characteristics beyond the fields entered by the user, creating an undisclosed tracking or profiling risk.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T14:36:42.872Z

### AI review details

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

- **Mechanism:** The code gathers browser and device characteristics, then adds the resulting fingerprint, page URL, user agent, and window dimensions to the form submission.

- **Rationale:** The package automatically collects browser fingerprint attributes and includes them with form submissions, without clear disclosure in the reviewed code. This may support fraud prevention, but the extra identifying data collection presents a user privacy risk.

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 84.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The package imports fingerprint code through its main entry point, which starts collecting browser attributes automatically., The fingerprint routine gathers browser characteristics such as canvas, installed fonts, language, storage availability, screen resolution, and platform., On form submission, the package sends the fingerprint alongside form data, the page URL, user agent, and window resolution.

- **Evidence against:** The package has no active install hook; its prepare script is empty., The fingerprint data is sent with an explicit form submission to a configurable endpoint, consistent with a possible form anti-abuse function., The public-IP lookup is registered in fingerprint.js but is not included in the browserTests list that runs automatically.
