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. The SDK silently reports runtime failures to Zero Hash’s collector with page origin, browser user agent, and selected JWT claims, and the package does not disclose this reporting or document an opt-out. The behavior is limited to widget loading failures and does not show transmission of the raw JWT, so this warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-30T15:24:35.510Z - **Finished:** 2026-10-30T15:25:16.939Z - **Download time:** 510 ms - **Static scan time:** 40 ms - **AI review time:** 40878 ms - **Total time:** 41429 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:** Undisclosed runtime diagnostic telemetry sends page and browser details plus selected JWT claims to the vendor collector when widget loading fails. - **Trigger:** An application explicitly calls render, followed by a script load error, timeout, or failure to define the widget component. - **Impact:** The vendor receives runtime and application-context data without a documented telemetry disclosure or opt-out; no raw JWT transmission was found. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-30T15:25:16.939Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK posts a Faro payload containing page origin, browser user agent, failure context, and selected participant/platform claims to its configured Zero Hash collector endpoint. - **Rationale:** The SDK silently reports runtime failures to Zero Hash’s collector with page origin, browser user agent, and selected JWT claims, and the package does not disclose this reporting or document an opt-out. The behavior is limited to widget loading failures and does not show transmission of the raw JWT, so this warrants a warning rather than a publish block. - **Network endpoints:** grafana-faro-collector.dev.0hash.com, grafana-faro-collector.cert.zerohash.com, grafana-faro-collector.zerohash.com, grafana-faro-collector.cert.zerohash.eu, grafana-faro-collector.zerohash.eu ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** On widget script-load failures, the SDK builds diagnostic data including the page origin, browser user agent, and selected JWT claims such as participant and platform codes., The SDK POSTs that diagnostic payload to a hard-coded Zero Hash Grafana Faro collector endpoint without a documented opt-out., The reporting callback runs on script load errors, timeouts, and component-definition failures during the widget loading flow. - **Evidence against:** The manifest has no lifecycle scripts; the package entry point exports a widget SDK., The widget script is loaded when the application calls render, and its URLs point to Zero Hash SDK CDN hosts., The collector payload contains selected decoded JWT claims, not the raw JWT; the available source does not show the token sent to the collector. ## Affected versions and remediation This report applies to @zerohash-sdk/fiat-account-link-js@1.15.12. - Review the evidence and your use of @zerohash-sdk/fiat-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.
