AI Security Review
scanned 1d ago · by lpm-firewall-aiThe package sends default runtime telemetry to its PostHog host, including the embedding domain and RunFrame activity, without disclosure in the inspected package source. The registry credential flow is user-triggered and goes to the registry service, so the evidence supports a telemetry warning rather than malicious exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the browser chunk initializes PostHog; rendering RunFrame captures activity. Telemetry can be disabled with TSCIRCUIT_TELEMETRY_DISABLED=true, and localhost tracking requires an explicit flag.
Impact
The package operator can observe the embedding site's hostname and basic RunFrame usage.
Mechanism
PostHog identifies the page by embedding domain or a generated persistent anonymous ID, then captures RunFrame activity properties.
AI rationale
The package sends default runtime telemetry to its PostHog host, including the embedding domain and RunFrame activity, without disclosure in the inspected package source. The registry credential flow is user-triggered and goes to the registry service, so the evidence supports a telemetry warning rather than malicious exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The shared browser chunk initializes PostHog automatically unless telemetry is disabled or the page is localhost without an explicit tracking flag.
- PostHog telemetry identifies the embedding domain or a persistent anonymous ID and includes the component's activity properties.
- Rendering RunFrame reports its source, component, embedded status, and active tab.
- The credential flow is tied to a visible Sign In button and uses the tscircuit registry API.
Evidence against
- The telemetry uses a project PostHog key and sends domain or random anonymous identity plus UI activity fields; no unrelated credentials or file contents were found in this flow.
- Registry login exchanges a login-page token with registry-api.tscircuit.com after the user clicks Sign In.
