AI Security Review
scanned 1d ago · by lpm-firewall-aiThe remote-library feature is consistent with the package's purpose, but its fetcher forwards configured credentials across redirects without a host check. This creates a concrete credential disclosure risk, so the package should be warned on rather than blocked as malicious.
Static reason
No blocking static signals were detected.
Trigger
After application startup, when an enabled remote library has no cached content and its configured source responds with a redirect.
Impact
A redirecting source can cause the configured code-fetch credential to be sent to another host.
Mechanism
The fetcher follows the redirect and recursively reuses the original authentication type, token and username without checking whether the destination host changed.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Critical Vulnerability with medium false-positive risk.
Evidence for warning
- On server startup, the service compiles enabled cloud libraries and loads their server code.
- When a remote library has no cached content, it fetches code using the library's configured URL and authentication settings.
- The fetcher sends a configured bearer token in the Authorization header.
- On an HTTP redirect, the fetcher repeats the request with the same authentication settings, potentially disclosing the token to the redirect destination.
- Library code runs in a VM context whose require function retains the full properties of Node's require.
Evidence against
- The package manifest has no lifecycle scripts.
- Remote code URLs and authentication settings come from library configuration; no fixed collector host or credential source is present in the reviewed paths.
- The VM execution and remote library fetching support the package's cloud-component feature.
