AI Security Review
scanned 12d ago · by lpm-firewall-aiThe source shows an ordinary CLI invocation can forward a license credential to a publisher-selected host outside the service used to validate it. This is concrete credential disclosure, so block publication.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Running the CLI when a license key is available and no fresh feed cache is present.
Impact
The publisher’s feed host receives a credential that is also used to validate the license with Polar.
Mechanism
Startup invokes the feed helper, which appends the license key to a request URL sent to getreadystack.com.
Attack narrative
The command-line entrypoint requests the rules feed before handling the user’s command. When a license key is available and the cached feed is stale, the helper sends that key in the query string to getreadystack.com; the same key is used with Polar’s license-validation service. The request has no recipient-specific consent gate.
AI rationale

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-line entry point.
- The CLI fetches the rules feed before processing its command-line arguments.
- The feed helper reads the license key from the environment or saved state and sends it as a query parameter to getreadystack.com.
- The same license key is submitted to Polar’s license-validation endpoint, establishing its credential use.
- No recipient-specific consent gate protects the feed request when a key is present and the feed cache is stale.
