## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 11 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:** 0.20.0
- **Selected version is latest:** Yes
- **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.

Initialization sends runtime telemetry to the configured API and the browser Origin header identifies the site using the SDK. The request is described in source, but no visible opt-out was found; the flagged account-hijack behavior was not confirmed.

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:** Initialization sends runtime telemetry that identifies the site using the SDK.

- **Trigger:** SDK init, at most once daily per project and browser.

- **Impact:** The service learns which site uses the SDK. This identifying runtime telemetry has no visible opt-out, so it warrants a warning.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T11:20:56.147Z

### AI review details

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

- **Mechanism:** After a five-second delay, POSTs project and SDK metadata to the configured API base; the browser also supplies the site's Origin header.

- **Rationale:** Initialization sends runtime telemetry to the configured API and the browser Origin header identifies the site using the SDK. The request is described in source, but no visible opt-out was found; the flagged account-hijack behavior was not confirmed.

- **Files touched:** browser localStorage key bugcatch:hello:{projectId}

- **Network endpoints:** {configured apiBase}/ingest/hello (default apiBase: http://localhost:3000)

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Initialization sends a once-daily \`/ingest/hello\` POST to the configured API base, using the project API key., The hello request relies on the browser Origin header, which identifies the site using the SDK., The hello payload includes project ID, SDK version, and whether user identification and context are configured., The package describes this request as reporting which site has the SDK installed, but provides no visible opt-out.

- **Evidence against:** The package is a browser bug-reporting SDK, and its report and sign-in requests use the configured API base., The inspected issue-following action is initiated by a user click; no account mutation was identified during initialization., The hello payload contains project and configuration metadata rather than credentials, files, or report contents.

## Affected versions and remediation

Public source snippet (untrusted):

```javascript
