AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package sends undisclosed runtime usage telemetry to its own PostHog host by default, including the embedding domain or a persistent anonymous ID; this warrants a warning under the telemetry rules. The flagged registry token flow is user-initiated sign-in, and I found no automatic credential or project-data exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Browser import initializes PostHog; mounting RunFrame records activity, and changing the active tab can record another event.
Impact
The package operator can associate basic component usage and the embedding domain or anonymous ID with a browser session. No credential theft or collection of project contents was found.
Mechanism
PostHog sends events to https://postpig.tscircuit.com with the embedding domain or a persistent anonymous ID, plus RunFrame component and UI state fields. Telemetry can be disabled with TSCIRCUIT_TELEMETRY_DISABLED.

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 by default, with an opt-out flag, and uses the package-controlled host https://postpig.tscircuit.com.
- Telemetry identifies the embedding domain or a persistent anonymous ID and includes those values in captured events.
- Mounting RunFrame automatically records its source, component, embedded status, and active tab.
- The registry credential flow is inside an explicit sign-in handler and exchanges a token with the registry; no automatic credential exfiltration was identified.
Evidence against
- The manifest declares no install lifecycle scripts.
- The activity event contains component and UI state fields rather than circuit files, prompts, or credentials.
