AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package sends default-on runtime analytics, including embed and anonymous identifiers, activity properties, and error details, to its analytics host; this warrants a warning. The flagged runner token flow is interactive and targets the tscircuit registry, and the reviewed source does not establish malicious data theft.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the browser bundle initializes PostHog; rendering the preview and encountering errors can produce telemetry.
Impact
The publisher can observe preview usage and receive error details without an explicit opt-in; the reviewed code does not establish credential or file-content theft.
Mechanism
PostHog receives embedding-domain and anonymous-ID identifiers, activity properties, and error messages and stacks. A runtime flag can disable telemetry.
AI rationale
The package sends default-on runtime analytics, including embed and anonymous identifiers, activity properties, and error details, to its analytics host; this warrants a warning. The flagged runner token flow is interactive and targets the tscircuit registry, and the reviewed source does not establish malicious data theft.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The shared browser bundle initializes PostHog at module evaluation; tracking is disabled only by a runtime flag or on localhost by default.
- Telemetry is sent to https://postpig.tscircuit.com and includes the embedding domain and anonymous ID.
- The preview component reports its identity, component name, embed status, and active tab as activity telemetry.
- Error telemetry sends error messages and stacks, and captures circuit JSON error messages and stacks.
Evidence against
- The flagged runner credential flow is an interactive sign-in flow that sends its login token to the configured tscircuit registry API.
- The observed telemetry does not show credentials, file contents, or machine details being sent.
