AI Security Review
scanned 3d ago · by lpm-firewall-aiThe source shows default runtime telemetry to the publisher’s analytics host that includes identifying domain or persistent-ID data, and the README does not disclose this collection. The reviewed code does not establish credential theft or project-content exfiltration, so this warrants a warning rather than a malicious verdict.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the shared browser chunk initializes PostHog; rendering CircuitJsonPreview triggers activity events.
Impact
The publisher can associate preview activity with an embedding website or persistent browser identifier. No credential theft or project-file exfiltration was identified in the reviewed flow.
Mechanism
The chunk initializes PostHog unless disabled by a global flag, then captures preview activity with the embedding domain or anonymous ID attached.
AI rationale
The source shows default runtime telemetry to the publisher’s analytics host that includes identifying domain or persistent-ID data, and the README does not disclose this collection. The reviewed code does not establish credential theft or project-content exfiltration, so this warrants a warning rather than a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The shared browser chunk initializes PostHog at module load and sends analytics to postpig.tscircuit.com; telemetry can be disabled through a global flag.
- Telemetry identifies users by the embedding domain or a persistent anonymous ID, and includes those identifiers in captured events.
- CircuitJsonPreview automatically reports activity including the active tab and whether it is embedded.
Evidence against
- The telemetry is limited in the inspected activity hook to preview usage fields and identity metadata; no credentials or project files were observed in those events.
- The registry token flow is in a sign-in handler and sends its temporary token to the tscircuit registry API.
- The manifest exports browser UI modules and declares no install or lifecycle scripts.
