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 scanner’s credential finding resolves to Coinbase Wallet’s WalletLink session authentication: the session ID and key are sent to WalletLink’s own API. The manifest has no install hook, and the connection code belongs to the browser checkout SDK’s wallet flow. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-11-01T21:01:17.982Z - **Finished:** 2026-11-01T21:02:17.236Z - **Download time:** 1268 ms - **Static scan time:** 11460 ms - **AI review time:** 46525 ms - **Total time:** 59254 ms 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 flagged credential flow is normal Coinbase Wallet session authentication. - **Trigger:** The flow is used as part of the wallet connection features when the SDK is used. - **Impact:** No unrelated credential collection or disclosure was found in the reviewed flow. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T21:02:17.236Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** WalletLink builds Basic authentication from its session ID and key and uses it for requests to its own events API. - **Rationale:** The scanner’s credential finding resolves to Coinbase Wallet’s WalletLink session authentication: the session ID and key are sent to WalletLink’s own API. The manifest has no install hook, and the connection code belongs to the browser checkout SDK’s wallet flow. - **Files touched:** dist/index.js, dist/dist-KGCCKZNC.js - **Network endpoints:** https://www.walletlink.org ### Review decision - **Verdict:** Clean - **Confidence:** 97.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes a framework-agnostic checkout SDK and exports dist/index.js as its entry point., The manifest scripts are build, development, type generation, lint, and test commands; no install lifecycle hook is declared., The checkout entry point requires a browser and exposes createFunkitCheckout, so the flagged wallet code is part of SDK use rather than install-time behavior., The flagged Authorization value is built from a WalletLink session ID and key, then sent to the WalletLink API for its events flow., The bundled Coinbase Wallet SDK sets the WalletLink service URL to https://www.walletlink.org and loads or creates a WalletLink session for its connection. ## Affected versions and remediation This report applies to @funkit/connect-js@0.4.0. - Review the evidence and your use of @funkit/connect-js@0.4.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
