## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 8 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:** 1.21.0
- **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 inspected manifest has no install lifecycle hooks, and the entrypoint implements a caller-rendered widget with Zerohash-hosted scripts and failure telemetry. JWT claims are decoded for region selection and included in telemetry metadata, but the observed collector endpoints are Zerohash-owned and no unrelated credential exfiltration or other attack behavior was established.

## Latest scan

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 malicious attack surface was identified. The SDK loads its Zerohash CryptoBuy widget on render and sends error telemetry to configured Zerohash collector endpoints.

- **Trigger:** A consumer renders the widget; telemetry is sent after a widget script load error.

- **Impact:** Expected widget loading and diagnostic reporting; inspected source does not establish unrelated credential exfiltration or malicious behavior.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T11:38:31.716Z

### AI review details

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

- **Mechanism:** The SDK loads a Zerohash-hosted widget script and POSTs diagnostic metadata to its Zerohash collector, including decoded JWT claims used as session attributes.

- **Rationale:** The inspected manifest has no install lifecycle hooks, and the entrypoint implements a caller-rendered widget with Zerohash-hosted scripts and failure telemetry. JWT claims are decoded for region selection and included in telemetry metadata, but the observed collector endpoints are Zerohash-owned and no unrelated credential exfiltration or other attack behavior was established.

- **Files touched:** dist/index.js

- **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:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest points consumers to the bundled JavaScript entrypoint and type declaration; it defines no lifecycle scripts., The type declaration describes a caller-provided JWT as widget authentication configuration., The bundled code POSTs error telemetry when script loading fails, and SDK setup passes the JWT claims into telemetry metadata., The telemetry and widget script hosts are Zerohash domains, and the widget script is loaded when the exported widget is rendered.

- **Evidence against:** No source evidence shows credential collection beyond decoding the caller-provided JWT claims for region routing and telemetry metadata., No package install hook, shell execution, persistence, or unrelated consumer-project mutation was identified.

## 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

- **Confidence:** 100.0%
- **Path:** dist/index.d.ts
- **Public source:** [View source](<https://unpkg.com/@zerohash-sdk/crypto-buy-js@1.21.0/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
```
