AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package performs undisclosed runtime telemetry to its publisher's service, so it warrants a warning under the telemetry rule. The inspected event payloads contain no personal, project or credential data, and the license-related requests serve the package's stated licensing function.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A human runs the CLI interactively; free runs send a usage event, and missing or invalid license checks can send a paywall event. Telemetry can be disabled with the documented-in-code environment flags.
Impact
The publisher receives usage and paywall event metadata. No host, user, project, file contents or system credentials are included in these event payloads.
Mechanism
The CLI posts the product slug, source and event reason to the package publisher's `/api/ev` endpoint.
AI rationale
The package performs undisclosed runtime telemetry to its publisher's service, so it warrants a warning under the telemetry rule. The inspected event payloads contain no personal, project or credential data, and the license-related requests serve the package's stated licensing function.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- An interactive free CLI run sends a `use` event containing the tool slug, CLI source and `free` reason to `getreadystack.com/api/ev`.
- The usage ping is gated on a TTY and can be disabled with `DO_NOT_TRACK=1` or `READYSTACK_NO_TELEMETRY`; the README does not disclose this telemetry.
- License or paywall handling also sends a `paywall` event containing the slug, source and reason to the same endpoint.
Evidence against
- The usage and paywall event payloads contain package-use metadata, not host, user, project, file or credential data.
- License validation sends a user-provided product license key to Polar's license validation endpoint.
- The rules feed is fetched using the product slug and license key, and its returned rules are added as data to the audit engine.
