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. The package is a browser SDK whose user-invoked render method loads its vendor widget from fixed CDN endpoints. No install-time behavior, local harvesting, secret exfiltration, persistence, or concealed execution was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-11T03:00:54.298Z - **Finished:** 2026-09-11T03:01:57.661Z - **Download time:** 778 ms - **Static scan time:** 56 ms - **AI review time:** 62528 ms - **Total time:** 63363 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. At runtime, an explicit widget render loads a fixed vendor CDN module and reports failures to vendor telemetry. - **Trigger:** The application constructs CryptoBuy and calls render on an HTML element. - **Impact:** The rendered widget executes code supplied by the configured ZeroHash CDN; this is aligned with the package's browser-widget purpose. - **Review source:** ai\_review - **Reviewed:** 2026-09-11T03:01:57.661Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Dynamic browser module loading with failure telemetry. - **Rationale:** The package is a browser SDK whose user-invoked render method loads its vendor widget from fixed CDN endpoints. No install-time behavior, local harvesting, secret exfiltration, persistence, or concealed execution was found. - **Network endpoints:** https://sdk-cdn.dev.0hash.com, https://sdk-cdn.cert.zerohash.com, https://sdk-cdn.zerohash.com, https://sdk-cdn.cert.zerohash.eu, https://sdk-cdn.zerohash.eu, https://sdk-cdn.gating.0hash.com, 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:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest has no lifecycle scripts and exports only the compiled browser SDK., A user call to render loads a fixed ZeroHash CDN module script into the page., On a script-load failure, telemetry posts limited error context to fixed ZeroHash collector hosts., The high-scanner-hit declaration file contains SDK type declarations and no executable install behavior. - **Evidence against:** No child-process, shell, filesystem, environment-harvesting, eval, or persistence code was found., Network activity is limited to the widget CDN and failure telemetry, activated by rendering the widget., The JWT is decoded only to select region and report limited partner context; the full token is not sent by this package. ## Affected versions and remediation This report applies to @zerohash-sdk/crypto-buy-js@1.19.2. - Review the evidence and your use of @zerohash-sdk/crypto-buy-js@1.19.2 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. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 2. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 3. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** dist/index.d.ts - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.
