AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package performs runtime analytics by default and sends identifying embed-domain data plus error messages and stacks to its analytics endpoint. This is a privacy risk warranting a warning; the registry credential flow is tied to an explicit user sign-in.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
When RunFrame renders or reports errors in a browser outside localhost; collection can be disabled with a global flag.
Impact
The analytics service receives identifying domain information and potentially user project details contained in errors or stacks.
Mechanism
PostHog sends telemetry to postpig.tscircuit.com, using the embedding domain as an identity and including error messages and stacks in exception reports.
AI rationale
The package performs runtime analytics by default and sends identifying embed-domain data plus error messages and stacks to its analytics endpoint. This is a privacy risk warranting a warning; the registry credential flow is tied to an explicit user sign-in.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The browser bundle initializes PostHog telemetry by default and sends it to https://postpig.tscircuit.com; a global flag can disable it.
- Telemetry identifies non-local embeds by their domain and includes that domain in the identity sent to analytics.
- On RunFrame errors, the package sends error messages and stacks to PostHog unless the telemetry-disable flag is set.
- RunFrame reports component activity and the active tab through its telemetry hook.
Evidence against
- The flagged registry bearer token is used in an explicit sign-in flow with the tscircuit registry.
- Project file uploads and events use the package’s runframe API for its editor functionality.
- The source provides a TSCIRCUIT_TELEMETRY_DISABLED opt-out flag.
