## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 6.42.1
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The package metadata and runtime behavior match Clerk’s authentication SDK. Its telemetry is disclosed, limited to development instances, and has a runtime disable control; the scanner’s network and dependency-bridge indicators are consistent with the SDK’s bundled integrations.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%

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:** No attack was identified. The observed network behavior is consistent with an authentication SDK, disclosed development-instance telemetry, and wallet or CAPTCHA integrations.

- **Trigger:** Normal SDK use; telemetry is gated to development instances, and wallet or CAPTCHA requests occur when those features are used.

- **Impact:** No malicious impact identified from the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-30T20:47:36.716Z

### AI review details

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

- **Mechanism:** The SDK sends buffered telemetry to clerk-telemetry.com and includes integrations that use external wallet and CAPTCHA services.

- **Rationale:** The package metadata and runtime behavior match Clerk’s authentication SDK. Its telemetry is disclosed, limited to development instances, and has a runtime disable control; the scanner’s network and dependency-bridge indicators are consistent with the SDK’s bundled integrations.

- **Network endpoints:** clerk-telemetry.com, rpc.wallet.coinbase.com, keys.coinbase.com, challenges.cloudflare.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package metadata identifies the expected Clerk JavaScript library and points to Clerk’s official repository., The SDK explicitly tells users that telemetry is collected when connected to development instances and links to opt-out information., Runtime telemetry is disabled outside development instances and can be disabled with a configuration flag or CLERK\_TELEMETRY\_DISABLED; buffered events and logs are sent to the declared Clerk telemetry endpoint.

- **Evidence against:** The SDK contains network calls, including telemetry POSTs to clerk-telemetry.com., The telemetry collector can receive event payloads and log context, so its runtime behavior merits review.
