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 package’s widget failure handler automatically sends runtime telemetry containing page and browser context plus selected JWT claims, with no disclosure or opt-out visible in the package. This is undisclosed telemetry rather than demonstrated credential exfiltration, so it warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-29T23:15:54.595Z - **Finished:** 2026-10-29T23:16:35.763Z - **Download time:** 1015 ms - **Static scan time:** 30 ms - **AI review time:** 40123 ms - **Total time:** 41168 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 widget loading failures along with application, browser, page, and JWT-claim context. - **Trigger:** When the embedded widget script fails to load, times out, or fails to define its custom element. - **Impact:** The collector receives application and browser context plus identifiers from the JWT claims. The source does not show transmission of the complete JWT. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T23:16:35.763Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The wrapper sends a JSON POST to an environment-selected Zerohash Grafana Faro collector, including selected decoded JWT claims, browser user agent, page origin, and script failure details. - **Rationale:** The package’s widget failure handler automatically sends runtime telemetry containing page and browser context plus selected JWT claims, with no disclosure or opt-out visible in the package. This is undisclosed telemetry rather than demonstrated credential exfiltration, so it 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 ### 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 failure, timeout, or missing custom element, the code reports diagnostic details., The diagnostic payload includes selected claims decoded from the supplied JWT, including participant and platform identifiers., The payload also includes the browser user agent and the embedding page’s origin., The report is sent as a JSON POST to a Zerohash Grafana Faro collector. - **Evidence against:** The package is a React wrapper for Zerohash’s crypto sell product, and loading its web component is central to that purpose., Reporting is limited to widget load failures and targets Zerohash collector endpoints; the source does not show the full JWT being sent. ## Affected versions and remediation This report applies to @zerohash-sdk/crypto-sell-react@1.15.10. - Review the evidence and your use of @zerohash-sdk/crypto-sell-react@1.15.10 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.
