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. Direct inspection shows a browser-focused React wallet UI with package-aligned authenticated services. Scanner findings conflate WebAuthn's \`eval\` field and a bundled Wasm loader with dynamic payload execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-13T04:20:19.570Z - **Finished:** 2026-08-13T04:21:19.630Z - **Download time:** 503 ms - **Static scan time:** 7442 ms - **AI review time:** 52114 ms - **Total time:** 60060 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. At runtime, the UI loads a same-vendor authentication iframe and performs authenticated wallet-backup/service requests. - **Trigger:** Application imports and initializes the EmbarkAI UI/wallet flows. - **Impact:** Expected authentication, MPC wallet, and encrypted-backup functionality; no install-time or covert execution found. - **Evidence paths:** package.json, dist/index.cjs, dist/iframe/main.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T04:21:19.630Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser iframe, WebAuthn, packaged Wasm, and authenticated API calls. - **Rationale:** Direct inspection shows a browser-focused React wallet UI with package-aligned authenticated services. Scanner findings conflate WebAuthn's \`eval\` field and a bundled Wasm loader with dynamic payload execution. - **Files touched:** package.json, dist/index.cjs, dist/iframe/main.js, dist/iframe/dkls23\_wasm\_bg.wasm - **Network endpoints:** https://auth.embarkai.io, https://api.embarkai.io/vault, https://api.embarkai.io/tss, https://dashboard.embarkai.io/api ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The flagged \`eval\` is a WebAuthn PRF extension property, not JavaScript evaluation., Wasm loader resolves the packaged \`dkls23\_wasm\_bg.wasm\` asset; no remote decoded payload execution was found., Runtime network calls implement authenticated wallet-backup and UI service operations. - **Evidence against:** package.json contains no preinstall, install, or postinstall hook., The package exports React UI bundles with sideEffects disabled., The iframe checks postMessage sender origin against its configured iframe origin., No credential harvesting, shell execution, filesystem access, persistence, or AI-agent configuration mutation found. ## Affected versions and remediation This report applies to @embarkai/ui-kit@0.4.90. - Review the evidence and your use of @embarkai/ui-kit@0.4.90 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.
