## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 9 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:** 1.21.11
- **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 sends runtime diagnostics to Zerohash collectors when the widget fails to load, including JWT-derived claims and browser/page context. This appears related to the SDK's purpose, but the telemetry is not documented in the README and has no apparent opt-out, so it warrants a warning.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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:** Undisclosed runtime diagnostics send integration and browser context to Zerohash telemetry endpoints.

- **Trigger:** A caller invokes render(), and widget script loading fails, times out, or the expected web component is not defined.

- **Impact:** Zerohash receives browser and integration identifiers without a documented telemetry opt-out in the package README.

- **Evidence paths:** dist/index.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-10-29T23:18:22.177Z

### AI review details

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

- **Mechanism:** The loader POSTs a Faro event containing JWT-derived claims, app and environment details, browser user agent, page origin, and failure context.

- **Rationale:** The package sends runtime diagnostics to Zerohash collectors when the widget fails to load, including JWT-derived claims and browser/page context. This appears related to the SDK's purpose, but the telemetry is not documented in the README and has no apparent opt-out, so it warrants a warning.

- **Network endpoints:** grafana-faro-collector.dev.0hash.com, grafana-faro-collector.cert.zerohash.com, grafana-faro-collector.zerohash.com, grafana-faro-collector.cert.zerohash.eu, grafana-faro-collector.zerohash.eu

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** When widget loading fails, the loader sends a diagnostic report to a Zerohash Faro collector., The report includes JWT-derived participant and platform claims, the browser user agent, and the page origin., Reporting is reached through the widget loading path initiated by render().

- **Evidence against:** The manifest has no lifecycle scripts, and importing the entry point does not itself send the report., The report is tied to widget loading failures and contains diagnostic fields related to the SDK integration., The collector hosts are Zerohash-branded endpoints, consistent with the package's stated widget purpose.
