AI Security Review
scanned 27d ago · by lpm-firewall-aiThe external POST is package-aligned SDK telemetry to the vendor API, and the manifest has no install-time lifecycle hook. The inspected source does not establish an attack surface.
Static reason
One or more suspicious static signals were detected.
Trigger
The client library queues telemetry events during use and flushes them periodically or when the event threshold is reached.
Impact
No confirmed credential theft or unrelated data forwarding was established.
Mechanism
It POSTs queued events with its SDK token to the vendor API telemetry path; the ordinary request omits browser credentials.
AI rationale
The external POST is package-aligned SDK telemetry to the vendor API, and the manifest has no install-time lifecycle hook. The inspected source does not establish an attack surface.

Decision evidence

Evidence for AI clean decision
- The manifest exposes a bundled library entrypoint and has only a prepublishOnly build hook, with no install-time hook.
- The flagged POST sends queued events with a bearer token to the SDK telemetry endpoint at the vendor API host.
