AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package sends undisclosed runtime usage and paywall telemetry to its own service during normal CLI use. The observed payloads are limited to package-use details and do not establish credential or project-data exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A free CLI scan, or a missing or rejected licence in an interactive CLI or MCP session; telemetry is skipped under the documented environment opt-outs and CI.
Impact
The vendor can observe package usage and licence-failure events. The reviewed event payloads do not include credentials, file contents, or project data.
Mechanism
The package sends a small event containing the product slug, CLI/MCP source, and use or paywall reason to the vendor's /api/ev endpoint. A stored licence key may also be sent to the vendor's product rules-feed endpoint.
AI rationale
The package sends undisclosed runtime usage and paywall telemetry to its own service during normal CLI use. The observed payloads are limited to package-use details and do not establish credential or project-data exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- A free CLI run sends a runtime usage event containing the product slug, source, and reason to getreadystack.com/api/ev.
- A missing or rejected licence can send a paywall event to the same endpoint; the code provides opt-outs and limits it to interactive or MCP sessions.
- The CLI starts a licence-feed check before processing its arguments; a saved or environment-provided licence key is sent to getreadystack.com for that product feed.
Evidence against
- The event payloads shown contain product-use details, not credentials, file contents, or project data.
- Licence validation sends the user-provided licence key to Polar's license-validation endpoint, consistent with the package's licensing purpose.
- Telemetry is suppressed by DO_NOT_TRACK, READYSTACK_NO_TELEMETRY, or CI, and usage events require an interactive session or MCP mode.
