## 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:** 3.6.0
- **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 source does not substantiate the scanner’s credential-exfiltration claim: the flagged Basic auth is derived from a Lydian session and sent to its configured link API. However, the bundled WalletConnect client sends runtime telemetry by default, and the README does not disclose it, so this warrants a warning rather than a clean verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 89.0%
- **Started:** 2026-10-31T08:12:14.483Z

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 WalletConnect runtime telemetry is enabled by default.

- **Trigger:** When checkout initialization reaches the WalletConnect client, such as during a wallet connection flow.

- **Impact:** Discloses app and SDK usage metadata to WalletConnect without a documented telemetry disclosure or opt-out in this package.

- **Evidence paths:** dist/chunks/mountEngine-CVnwr305.js, dist/chunks/index-9i2S104v.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-10-31T08:13:30.999Z

### AI review details

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

- **Mechanism:** The bundled event client sends an INIT event and other telemetry to WalletConnect’s pulse endpoint; the INIT event includes a generated client ID and user-agent data, and events include the app domain.

- **Rationale:** The source does not substantiate the scanner’s credential-exfiltration claim: the flagged Basic auth is derived from a Lydian session and sent to its configured link API. However, the bundled WalletConnect client sends runtime telemetry by default, and the README does not disclose it, so this warrants a warning rather than a clean verdict.

- **Network endpoints:** https://pulse.walletconnect.org/batch

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 89.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The bundled WalletConnect event client defaults telemetry on and creates an INIT event containing a client ID and user-agent data., It sends telemetry events to https://pulse.walletconnect.org/batch with the configured project ID and event payload., The wallet engine loads on checkout initialization, and the WalletConnect client is created when its wallet connection service is used., The README describes the WalletConnect project ID as powering wallet connections but does not disclose this telemetry., The flagged Basic auth value is built from the Lydian session ID and secret and used with the configured link API URL.

- **Evidence against:** The manifest entry is a web checkout SDK; its package script is a prepublishOnly CI guard, not an install hook., The engine is loaded on demand rather than when the package entry is imported., The telemetry payload shown includes a generated client ID, user-agent data and app domain; the reviewed code does not show unrelated credentials being collected or sent.

## Affected versions and remediation

This report applies to @lydianpay/sdk-web@3.6.0.

- Review the evidence and your use of @lydianpay/sdk-web@3.6.0 before allowing it. Restrict the permissions described in this report.
