AI Security Review
scanned 5d ago · by lpm-firewall-aiThe bundle sends undisclosed runtime activity and error telemetry to the package's PostHog host, including circuit JSON error messages and stacks. A browser flag disables telemetry, so this is suspicious runtime telemetry rather than clear credential exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the preview bundle initializes telemetry; rendering the preview and producing errors can send events.
Impact
The package sends runtime and application error details without disclosure in the reviewed README; a browser flag can disable telemetry.
Mechanism
PostHog receives preview activity fields and exception messages and stacks, including circuit JSON errors.
AI rationale
The bundle sends undisclosed runtime activity and error telemetry to the package's PostHog host, including circuit JSON error messages and stacks. A browser flag disables telemetry, so this is suspicious runtime telemetry rather than clear credential exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The preview bundle initializes PostHog at module load and uses https://postpig.tscircuit.com.
- Rendering CircuitJsonPreview records activity fields including the embed state and active tab.
- When errors occur, the bundle sends error messages and stacks, including circuit JSON errors, to PostHog.
Evidence against
- The package is a React component for running tscircuit and displaying circuit previews.
- Telemetry can be disabled with the TSCIRCUIT_TELEMETRY_DISABLED browser flag.
- The reviewed sign-in flow sends its login-page token to the tscircuit registry API.
