Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This is a legitimate widget SDK whose hosted script loads on an explicit render call. However, load failures automatically send decoded JWT claims and browser/page metadata to the vendor’s collector, with no documented opt-out, so the runtime telemetry warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-31T09:50:06.989Z - **Finished:** 2026-10-31T09:51:02.525Z - **Download time:** 762 ms - **Static scan time:** 42 ms - **AI review time:** 54731 ms - **Total time:** 55536 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:** Runtime error telemetry reports failed widget loads to Zerohash’s Faro collector. - **Trigger:** An application calls render(), and the hosted widget fails to load or define its component. - **Impact:** Zerohash receives partner or participant context and browser/page metadata without a documented opt-out. - **Evidence paths:** dist/index.js, dist/index.d.ts, README.md - **Review source:** ai\_review - **Reviewed:** 2026-10-31T09:51:02.525Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK POSTs diagnostics, decoded JWT claims, browser user agent and page origin to the configured environment’s collector. - **Rationale:** This is a legitimate widget SDK whose hosted script loads on an explicit render call. However, load failures automatically send decoded JWT claims and browser/page metadata to the vendor’s collector, with no documented opt-out, so the runtime telemetry warrants a warning. - **Network endpoints:** https://grafana-faro-collector.dev.0hash.com/collect, https://grafana-faro-collector.cert.zerohash.com/collect, https://grafana-faro-collector.zerohash.com/collect, https://grafana-faro-collector.cert.zerohash.eu/collect, https://grafana-faro-collector.zerohash.eu/collect, https://sdk-cdn.dev.0hash.com/crypto-account-link-web/index.js, https://sdk-cdn.cert.zerohash.com/crypto-account-link-web/index.js, https://sdk-cdn.zerohash.com/crypto-account-link-web/index.js, https://sdk-cdn.cert.zerohash.eu/crypto-account-link-web/index.js, https://sdk-cdn.zerohash.eu/crypto-account-link-web/index.js, https://sdk-cdn.gating.0hash.com/crypto-account-link-web/index.js, http://localhost:5173/crypto-account-link-web/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** When widget loading fails, the loader builds a report containing decoded participant, platform and region claims from the configured JWT, plus app and failure context., The report includes the browser user agent and the current page origin., The loader POSTs the report as JSON to a Faro collector; the declaration comments acknowledge sending failures and JWT claims to Faro., The SDK config exposes no telemetry opt-out, and the README does not mention this reporting. - **Evidence against:** The SDK loads its hosted widget only when the application calls render(); importing the package does not initiate this flow., The request sends decoded claims rather than the raw JWT, and the collector belongs to Zerohash, the SDK publisher. ## Affected versions and remediation This report applies to @zerohash-sdk/crypto-account-link-js@1.15.12. - Review the evidence and your use of @zerohash-sdk/crypto-account-link-js@1.15.12 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.
