## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 8 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:** 1.21.10
- **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 performs undisclosed runtime telemetry on widget script-load failures, sending browser and page context plus selected JWT claims to its own collector. This is a warning-level telemetry finding, not evidence of credential theft or unrelated collection.

## Latest scan

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 error telemetry is sent to Zerohash's collector when the widget script fails to load.

- **Trigger:** An application renders the widget and its script load fails or times out.

- **Impact:** The collector receives browser and application context without a documented telemetry disclosure or opt-out.

- **Evidence paths:** dist/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-29T23:18:18.099Z

### AI review details

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

- **Mechanism:** The SDK posts a failure report containing app/environment details, selected JWT claims, browser user agent, and page origin.

- **Rationale:** The package performs undisclosed runtime telemetry on widget script-load failures, sending browser and page context plus selected JWT claims to its own collector. This is a warning-level telemetry finding, not evidence of credential theft or unrelated collection.

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The SDK configures regional Zerohash Grafana Faro collectors at \`/collect\`., When its widget script fails to load, the SDK reports the failure, including the script URL, reason, and decoded JWT claims., The report payload includes a random session ID, app and environment details, selected JWT claims, browser user agent, and page origin., The SDK sends the report with a JSON POST request., The documented flow loads the widget when the application calls \`render()\`, so the report is runtime behavior rather than an install-time action.

- **Evidence against:** The report goes to Zerohash's own collector hosts, matching the SDK's purpose., The report is limited to script-load failures; the inspected code does not send the JWT token itself., The README documents an explicit widget render call as part of normal use.

## Affected versions and remediation
