AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package’s browser bundle sends runtime telemetry to its own analytics host by default, including the embedding page’s hostname and diagnostic error details. This is an identifying telemetry disclosure issue; the inspected code did not establish credential theft or unrelated file collection.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the browser bundle initializes PostHog; preview activity and errors trigger further events.
Impact
The service receives identifying domain information and runtime diagnostics without an explicit opt-in. No credential or unrelated file exfiltration was identified.
Mechanism
The bundle sends events to postpig.tscircuit.com, using the embedding page’s hostname as an identity and including UI state; error reporting can include messages and stacks.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Browser bundle initializes PostHog telemetry by default and sends it to postpig.tscircuit.com.
- Telemetry derives an identity from the embedding page’s hostname and includes that domain in captured events.
- The preview reports UI activity including the selected tab and whether it is web embedded.
- Runtime error messages and stacks are sent unless telemetry is disabled through a global setting.
Evidence against
- The reported activity is limited to preview state and an anonymous or domain identity; no credential theft or unrelated file collection was established.
- Registry sign-in is initiated by a user action and uses the tscircuit registry API.
