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. Source inspection found package-aligned Xumm authentication: JWTs are sent to Xumm API and OAuth endpoints, and postMessage origins are checked. No unrelated credential exfiltration or other attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T03:43:34.760Z - **Finished:** 2026-10-10T03:44:19.855Z - **Download time:** 4099 ms - **Static scan time:** 8912 ms - **AI review time:** 32083 ms - **Total time:** 45095 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 in the inspected credential-handling paths. The package uses JWTs for Xumm wallet authentication and sends them to Xumm endpoints. - **Trigger:** A consumer uses the wallet authentication flow, with automatic restoration gated by its options. - **Impact:** No unrelated credential recipient or confirmed attack impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T03:44:19.855Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle attaches a bearer token to Xumm API calls and sends an OAuth access token to Xumm's userinfo endpoint; it restricts accepted authentication messages to Xumm origins. - **Rationale:** Source inspection found package-aligned Xumm authentication: JWTs are sent to Xumm API and OAuth endpoints, and postMessage origins are checked. No unrelated credential exfiltration or other attack behavior was established. - **Files touched:** dist/xrpl-wallet-kit.iife.js - **Network endpoints:** https://oauth2.xumm.app/userinfo, https://xumm.app, https://oauth2.xumm.app ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes the flagged bundle as the package entrypoint., The bundle sends bearer tokens to its fixed Xumm API endpoint and confines JWT requests to its listed API endpoints., The OAuth userinfo flow accepts messages only from Xumm origins and sends its token to Xumm's OAuth service., Automatic token restoration is conditional on caller options. - **Evidence against:** The inspected credential use is part of the Xumm wallet authentication flow; no unrelated recipient or credential exfiltration was identified. ## Affected versions and remediation This report applies to @xrpl-wallet-kit/browser@0.1.19. - Review the evidence and your use of @xrpl-wallet-kit/browser@0.1.19 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.
