A JavaScript SDK that enables frontend applications to seamlessly integrate with the Connect Crypto Buy product.
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package performs undisclosed runtime telemetry on widget script-load failures, sending browser and page context plus selected JWT claims to its own collector. This is a warning-level telemetry finding, not evidence of credential theft or unrelated collection.
Static reason
No blocking static signals were detected.
Trigger
An application renders the widget and its script load fails or times out.
Impact
The collector receives browser and application context without a documented telemetry disclosure or opt-out.
Mechanism
The SDK posts a failure report containing app/environment details, selected JWT claims, browser user agent, and page origin.
AI rationale
The package performs undisclosed runtime telemetry on widget script-load failures, sending browser and page context plus selected JWT claims to its own collector. This is a warning-level telemetry finding, not evidence of credential theft or unrelated collection.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The SDK configures regional Zerohash Grafana Faro collectors at `/collect`.
- When its widget script fails to load, the SDK reports the failure, including the script URL, reason, and decoded JWT claims.
- The report payload includes a random session ID, app and environment details, selected JWT claims, browser user agent, and page origin.
- The SDK sends the report with a JSON POST request.
- The documented flow loads the widget when the application calls `render()`, so the report is runtime behavior rather than an install-time action.
Evidence against
- The report goes to Zerohash's own collector hosts, matching the SDK's purpose.
- The report is limited to script-load failures; the inspected code does not send the JWT token itself.
- The README documents an explicit widget render call as part of normal use.
