AI Security Review
scanned 6d ago · by lpm-firewall-aiThe postinstall telemetry path requires a previously recorded affirmative preference and sends limited anonymous usage data. Runtime telemetry is described in a first-run prompt, and the reviewed credential use sends the key to the configured Extenshi catalog service for a requested command.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The install ping requires a saved telemetry:true preference. Runtime telemetry follows the CLI consent prompt or an existing preference; API requests occur during CLI commands.
Impact
The observed telemetry reports package and runtime details with an anonymous install ID. No credential exfiltration or unrelated account action was identified.
Mechanism
The hook sends an anonymous install event to PostHog. The risk command sends its configured API key to the catalog BFF for the requested lookup.
AI rationale
The postinstall telemetry path requires a previously recorded affirmative preference and sends limited anonymous usage data. Runtime telemetry is described in a first-run prompt, and the reviewed credential use sends the key to the configured Extenshi catalog service for a requested command.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook is present, but it exits unless the saved configuration already has telemetry set to true.
- The install event contains an anonymous install ID and package, runtime, and platform details.
- The CLI asks about anonymous usage telemetry before recording command events and describes what it collects.
- The risk command sends its API key as a bearer token to the configured catalog BFF for the requested lookup.
