AI Security Review
scanned 4d ago · by lpm-firewall-aiThe source sends the embedding site’s hostname and preview activity to the package’s telemetry host by default, without disclosure in the README. This is suspicious runtime telemetry; the reviewed code does not show credentials or project files being sent through this telemetry path.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
PostHog initialization runs when the shared browser chunk loads; preview activity is captured when the preview is used.
Impact
The package vendor can learn which sites embed the preview and how it is used.
Mechanism
The code identifies the embed domain from the referrer or browser hostname and includes it with activity properties in telemetry. A global flag can disable telemetry.
AI rationale
The source sends the embedding site’s hostname and preview activity to the package’s telemetry host by default, without disclosure in the README. This is suspicious runtime telemetry; the reviewed code does not show credentials or project files being sent through this telemetry path.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The shared chunk initializes PostHog automatically, with a global flag to disable telemetry.
- Telemetry derives the embedding domain from the referrer or browser hostname and includes it in captured events.
- The preview records activity properties including the active tab and whether it is web embedded.
Evidence against
- The package is a React preview and editor for tscircuit projects.
- Project file synchronization uses the frame API base, defaulting to /api.
- The reviewed registry sign-in flow runs from a user-triggered sign-in handler.
