## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 9 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 1.21.3
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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 entrypoint implements an explicitly rendered crypto-buy widget, loading its vendor CDN script and reporting load failures to environment-specific Zerohash collectors. I found no lifecycle hook or source evidence of credential harvesting, unrelated destinations, or malicious execution.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 90.0%

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 attack was identified. The package loads its widget when rendered and sends diagnostic data to Zerohash collector endpoints after a loading failure.

- **Trigger:** A consumer renders the widget and its script fails to load or define the expected component.

- **Impact:** This supports widget delivery and operational diagnostics; inspected source does not establish credential exfiltration or another attack.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T11:39:00.124Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The SDK loads the widget from its configured CDN and posts failure diagnostics, including app, browser, page, and widget-loading metadata, to an environment-selected collector.

- **Rationale:** The entrypoint implements an explicitly rendered crypto-buy widget, loading its vendor CDN script and reporting load failures to environment-specific Zerohash collectors. I found no lifecycle hook or source evidence of credential harvesting, unrelated destinations, or malicious execution.

- **Files touched:** package.json, dist/index.js, dist/index.d.ts

- **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, 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

### Review decision

- **Verdict:** Clean

- **Confidence:** 90.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json exposes the distributed JavaScript module and declaration file, with no lifecycle scripts., The declarations describe the JWT as widget authentication configuration., Rendering loads the widget script; failures produce a diagnostic POST to the configured environment collector., The loader sends a script from the SDK CDN and chooses collector endpoints from the configured environment.

## 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](<https://unpkg.com/@zerohash-sdk/crypto-buy-js@1.21.3/dist/index.d.ts>)

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 = 1
```

### 4. Low: Suspicious Lifecycle Evidence
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@zerohash-sdk/crypto-buy-js@1.21.3/package.json>)

package.json exposes the distributed JavaScript module and declaration file, with no lifecycle scripts.

Public source snippet (untrusted):

```json
"type": "module",
  "main": "./dist/index.js",
  "module": "./dist/index.js",
  "types": "./dist/index.d.ts",
  "license": "MIT",
  "exports": {

- **Path:** dist/index.d.ts
- **Public source:** [View source](<https://unpkg.com/@zerohash-sdk/crypto-buy-js@1.21.3/dist/index.d.ts>)

The declarations describe the JWT as widget authentication configuration.

Public source snippet (untrusted):

```typescript
declare interface BaseConfig<TEvent = AppEvent> extends CommonCallbacks<TEvent> {
    /**
     * JWT token used for authentication. Provide/update it via `setJWT`
     * (`updateConfig({ jwt })`).
     */

```javascript
try {
      await this.ensureScriptLoaded();
      const r = this.createWebComponent();
      t.innerHTML = "", t.appendChild(r), this.state.container = t, this.state.element = r, this.state.initialized = !0;
    } catch (r) {
