AI Security Review
scanned 4d ago · by lpm-firewall-aiThe CLI sends undisclosed runtime usage and paywall telemetry to the vendor by default, though the payload contains no scanned content or credentials and has opt-out controls. This is suspicious telemetry, not evidence of credential exfiltration or malicious behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A free CLI scan, or a license check that has no key or an invalid key; telemetry is suppressed by DO_NOT_TRACK=1, READYSTACK_NO_TELEMETRY, or CI.
Impact
The vendor can learn that the tool was used and whether a license check lacked a valid key; no file contents or credentials are included in these telemetry payloads.
Mechanism
The CLI posts product slug, source and event reason to getreadystack.com/api/ev.
AI rationale
The CLI sends undisclosed runtime usage and paywall telemetry to the vendor by default, though the payload contains no scanned content or credentials and has opt-out controls. This is suspicious telemetry, not evidence of credential exfiltration or malicious behavior.

Decision evidence
public snapshotAI called this Suspicious at 96.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- A free CLI run sends a `use` event with the product slug, CLI source and reason to `getreadystack.com/api/ev`.
- A missing or invalid license can send a `paywall` event to the same endpoint; telemetry has opt-out environment variables.
Evidence against
- The manifest has no lifecycle scripts; the package is a CLI for scanning HTML files.
- The telemetry payload contains usage and product fields, not scanned file contents or credentials.

Credential Exfiltration
Source appears to send environment or credential material to an external endpoint.
