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 not concrete malware, but it exposes a remote-code execution capability in the customer browser and has incomplete static coverage because the declaration artifact contains implementation code. Warn rather than block because activation is explicit and no malicious install-time or local compromise behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-11T17:50:57.684Z - **Finished:** 2026-09-11T17:52:41.453Z - **Download time:** 252 ms - **Static scan time:** 62 ms - **AI review time:** 103454 ms - **Total time:** 103769 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:** Calling render() loads a remote module into the application page. On a load failure, the package sends limited browser and JWT-claim context to Zerohash telemetry collectors. - **Trigger:** An application constructs CryptoSell and calls render() in a browser. - **Impact:** A CDN compromise or unreviewed remote update could execute code in the embedding page; telemetry discloses browser metadata and selected JWT claims. - **Evidence paths:** dist/index.js, dist/index.d.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-11T17:52:41.453Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Dynamic CDN module injection with failure telemetry. - **Rationale:** This is not concrete malware, but it exposes a remote-code execution capability in the customer browser and has incomplete static coverage because the declaration artifact contains implementation code. Warn rather than block because activation is explicit and no malicious install-time or local compromise behavior was found. - **Files touched:** dist/index.js - **Network endpoints:** sdk-cdn.dev.0hash.com, sdk-cdn.cert.zerohash.com, sdk-cdn.zerohash.com, sdk-cdn.cert.zerohash.eu, sdk-cdn.zerohash.eu, sdk-cdn.gating.0hash.com, 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:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Rendering dynamically injects and executes a module script fetched from a CDN, so remotely changed content runs in the host page., Failure telemetry posts browser user agent, page origin, and selected JWT claims to collector endpoints., The published declaration file contains implementation bodies and an import-meta URL override, making its static coverage unreliable. - **Evidence against:** package.json has no lifecycle scripts or dependencies., Network loading occurs only after an application calls render(); no install-time or import-time action was found., The inspected code contains no filesystem access, shell execution, credential harvesting, or destructive behavior. ## Affected versions and remediation This report applies to @zerohash-sdk/crypto-sell-js@1.14.3. - Review the evidence and your use of @zerohash-sdk/crypto-sell-js@1.14.3 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. 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. Public source snippet (untrusted): ```typescript stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 2 ``` ### 4. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 86.0% - **Path:** dist/index.js - **Public source:** [View source]() Rendering dynamically injects and executes a module script fetched from a CDN, so remotely changed content runs in the host page. Public source snippet (untrusted): ```javascript const d = document.createElement("script"); d.id = h, d.src = l, d.type = "module", d.async = !0, d.onload = () => { setTimeout(() => { m || (customElements.get(t) ?

Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 86.0% - **Path:** dist/index.js - **Public source:** [View source]() Failure telemetry posts browser user agent, page origin, and selected JWT claims to collector endpoints. Public source snippet (untrusted): ```javascript const r = F(), o = globalThis.__ZH_WEB_SDK_VERSION__, n = {}; e.claims.participantCode && (n.participant_code = e.claims.participantCode), e.claims.platformName && (n.platform_name = e.claims.platformName), e.claims.platformCode && (n.platform_code = e.claims.platformCode), e.claims.region && (n.region = e.claims.region), o && (n.zh_web_sdk_version = o); const a = { meta: { app: { name: e.appName, version: t ??

Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 86.0% - **Path:** dist/index.d.ts - **Public source:** [View source]() The published declaration file contains implementation bodies and an import-meta URL override, making its static coverage unreliable.
