AI Security Review
scanned 4d ago · by lpm-firewall-aiThe CLI forwards a Polar license key to getreadystack.com automatically at startup, including when the user did not request a rules-feed operation. This is credential exfiltration to a host other than the key’s validation service.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Running the CLI, before command-line arguments are parsed.
Impact
The license credential is disclosed to a host other than its validation service without an explicit user request.
Mechanism
pullFeed reads the license key from READYSTACK_LICENSE or the local saved state and places it in a query parameter sent to getreadystack.com; the key is otherwise submitted to api.polar.sh for validation.
Attack narrative
When cli.js starts, it calls pullFeed before handling the requested command. pullFeed loads the saved or environment-provided license key and sends it in a URL query to getreadystack.com. The same key is submitted to api.polar.sh for license validation, so the vendor’s automatic rules-feed request discloses a credential to a different host without an explicit request to do so.
AI rationale
The CLI forwards a Polar license key to getreadystack.com automatically at startup, including when the user did not request a rules-feed operation. This is credential exfiltration to a host other than the key’s validation service.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- The manifest exposes cli.js as the package command.
- license.js sends license keys to api.polar.sh for validation.
- On every CLI startup, pullFeed reads READYSTACK_LICENSE or the saved key and adds it as a key query parameter to a getreadystack.com request.
- cli.js calls pullFeed before parsing arguments, so the forwarding can happen without a license-related command.
Evidence against
- The package is a German retention-period linting tool, and its CLI scans files locally.
- License validation against Polar and a rules feed from getreadystack.com are consistent with the described paid features.
- The CLI also sends limited package-use and paywall telemetry, with opt-out checks.
