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 manifest identifies a React UI kit with no install hooks, and the flagged credential handling is used for an explicit server-backup feature. It exchanges the supplied access token for a scoped EmbarkAI vault token and uploads encrypted keyshare data to that service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-31T08:57:32.618Z - **Finished:** 2026-10-31T08:58:05.108Z - **Download time:** 509 ms - **Static scan time:** 6217 ms - **AI review time:** 25762 ms - **Total time:** 32490 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 flows support explicit backup and related UI features. - **Trigger:** A caller requests server backup through the iframe’s CREATE\_BACKUP message handler. - **Impact:** The reviewed flow sends encrypted backup data and a scoped token to the package’s EmbarkAI service as part of the requested backup. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T08:58:05.108Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler validates the SDK channel; backup encrypts keyshare data, exchanges the provided access token for a scoped resource token, then uploads to the Share Vault. - **Rationale:** The manifest identifies a React UI kit with no install hooks, and the flagged credential handling is used for an explicit server-backup feature. It exchanges the supplied access token for a scoped EmbarkAI vault token and uploads encrypted keyshare data to that service. - **Network endpoints:** https://api.embarkai.io/vault/v1/shares/me, https://api.embarkai.io/api/auth/token/exchange ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes a React UI kit and exposes bundled UI entry points; it declares no install lifecycle scripts., The server backup flow exchanges an access token for a narrowly scoped Share Vault resource token and sends that token to the package’s EmbarkAI vault endpoint., Server backup encrypts keyshare data before upload., Backup runs through an explicit CREATE\_BACKUP request after SDK channel validation. ## Affected versions and remediation This report applies to @embarkai/ui-kit@0.4.128. - Review the evidence and your use of @embarkai/ui-kit@0.4.128 before allowing it.
