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. Static inspection shows suspicious primitives are attributable to browser wallet/auth functionality: bundled wasm-bindgen glue, user-invoked OAuth/backup/network calls, and iframe messaging. There is no lifecycle execution, hidden exfiltration, remote decoded code execution, persistence, destructive action, or AI-agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-07-03T00:19:32.973Z - **Finished:** 2026-07-03T00:20:18.683Z - **Download time:** 762 ms - **Static scan time:** 3390 ms - **AI review time:** 41556 ms - **Total time:** 45710 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 confirmed malicious attack surface is established. The package is a browser React UI kit for EmbarkAI/Lumia authentication, iframe wallet operations, TSS keyshares, backups, and OAuth integrations. - **Trigger:** User imports the UI kit and invokes provider/auth/wallet/backup/OAuth flows in a browser. - **Impact:** Expected auth, wallet signing, keyshare backup/restore, and UI behavior; no unconsented install-time execution or credential harvesting found. - **Evidence paths:** package.json, dist/index.cjs, dist/index.js, dist/iframe/main.js, dist/iframe/dkls23\_wasm\_bg.wasm, dist/iframe/index.html, dist/iframe/oauth/x.js, dist/iframe/oauth/telegram.js - **Review source:** ai\_review - **Reviewed:** 2026-07-03T00:20:18.683Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Package-aligned browser fetch, iframe postMessage, localStorage, OAuth popup, and bundled WASM crypto operations. - **Rationale:** Static inspection shows suspicious primitives are attributable to browser wallet/auth functionality: bundled wasm-bindgen glue, user-invoked OAuth/backup/network calls, and iframe messaging. There is no lifecycle execution, hidden exfiltration, remote decoded code execution, persistence, destructive action, or AI-agent control-surface mutation. - **Network endpoints:** https://api.embarkai.io/tss, https://api.embarkai.io/vault, https://api.embarkai.io/on-ramp/api, https://auth.embarkai.io, https://dashboard.embarkai.io/api, https://dashboard.embarkai.io/api/public/project, https://apis.google.com/js/api.js, https://accounts.google.com/gsi/client, https://www.googleapis.com/drive/v3/files, https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart, https://telegram.org/js/telegram-widget.js?22, https://api.etherscan.io/v2/api ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** dist/iframe/main.js ships dkls23\_wasm\_bg.wasm and wasm-bindgen glue with new Function/module.require imports., dist/index.cjs and dist/iframe/main.js send auth tokens/keyshare data to EmbarkAI vault/TSS APIs during wallet backup/auth flows., dist/iframe/oauth/telegram.js loads Telegram widget and posts OAuth result to opener with wildcard target. - **Evidence against:** package.json has no install/preinstall/postinstall lifecycle hooks; scripts are build/dev only., dist/index.cjs import-time action only injects packaged CSS into document head when a browser document exists., Network calls are aligned with UI wallet/auth, backup, bridge, explorer, and OAuth features and are user/runtime invoked., dist/iframe/main.js fetches local dkls23\_wasm\_bg.wasm via import.meta.url; no remote decoded payload found., No child\_process usage found; scanner hit appears to be noisy., postMessage handling checks iframe origin for SDK messages and OAuth popup origins are constrained by iframe origin in caller. ## Affected versions and remediation This report applies to @embarkai/ui-kit@0.4.39. - Review the evidence and your use of @embarkai/ui-kit@0.4.39 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.
