No install-time execution or concrete malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-11T17:50:57.703Z - **Finished:** 2026-09-11T17:52:18.684Z - **Download time:** 251 ms - **Static scan time:** 46 ms - **AI review time:** 80683 ms - **Total time:** 80981 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 confirmed malicious attack surface was established. An explicit browser render loads the vendor widget and reports widget-load failures. - **Trigger:** An application constructs CryptoBuy and calls render(). - **Impact:** The configured CDN script executes in the embedding page; failure telemetry includes limited browser and JWT-claim context. - **Review source:** ai\_review - **Reviewed:** 2026-09-11T17:52:18.684Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser-side CDN widget loading with failure telemetry. - **Rationale:** This is a browser widget SDK with user-invoked, package-aligned remote loading and diagnostics. No install-time execution or concrete malicious behavior was found. - **Network endpoints:** sdk-cdn.zerohash.com, grafana-faro-collector.zerohash.com ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The browser SDK loads a module script from an environment-selected vendor CDN when its render path runs., On widget-load failure it sends diagnostic telemetry that includes selected JWT claims, browser user agent, and page origin., The manifest exposes module and type entrypoints only; it contains no lifecycle scripts. - **Evidence against:** Loading occurs only after an application constructs and renders the widget., CDN and telemetry destinations are fixed environment maps, not attacker-supplied URLs., No install hook, shell execution, dynamic code evaluation, filesystem access, or project mutation was found. ## Affected versions and remediation This report applies to @zerohash-sdk/crypto-buy-js@1.19.3. - Review the evidence and your use of @zerohash-sdk/crypto-buy-js@1.19.3 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.
