AI Security Review
scanned 6d ago · by lpm-firewall-aiThe default browser entry loads telemetry that reports project-related error messages and stacks to a remote PostHog host, with only an undocumented window-level opt-out. This is a real privacy risk, but the source does not establish credential theft or deliberate collection of complete project files, so it warrants a warning rather than a malicious verdict.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the browser entry initializes PostHog; rendering RunFrame with errors triggers exception reporting unless a window-level disable flag is set.
Impact
Project-specific diagnostics may be disclosed to the telemetry service without clear user consent.
Mechanism
The telemetry hook passes error text and stacks, including each circuit JSON error's message and stack, to PostHog capture.
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The default preview entry imports the added shared chunk, which calls `initPostHog()` at module load.
- The chunk sends telemetry to `https://postpig.tscircuit.com`; telemetry can be disabled only by setting the `TSCIRCUIT_TELEMETRY_DISABLED` window variable before it runs.
- RunFrame passes `errorMessage`, `errorStack`, and `circuitJsonErrors` to a hook that submits exceptions, including circuit error messages and stacks, to PostHog.
- The README does not mention telemetry.
Evidence against
- The manifest declares no install lifecycle scripts.
- The bearer token flagged by the scanner is used in the registry sign-in flow; I found no evidence that it is sent to the telemetry host.
