AI Security Review
scanned 1d ago · by lpm-firewall-aiThe package is designed to fetch and load configured cloud-library code, but its authenticated fetcher forwards credentials across redirects without checking the destination origin. This creates a credential-disclosure vulnerability, so warn rather than block the package itself.
Static reason
No blocking static signals were detected.
Trigger
At application startup, an enabled remote library without cached code is fetched, and its server responds with a redirect.
Impact
A remote server or compromised source can redirect the request to another host and receive the library's bearer token or basic-auth credentials.
Mechanism
The fetcher follows the Location URL and calls itself again with the original authentication type, token, and username, without restricting the redirect origin.
AI rationale
The package is designed to fetch and load configured cloud-library code, but its authenticated fetcher forwards credentials across redirects without checking the destination origin. This creates a credential-disclosure vulnerability, so warn rather than block the package itself.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Critical Vulnerability with medium false-positive risk.
Evidence for warning
- On application startup, the service loads enabled cloud libraries.
- When an enabled remote library has no cached code, the service passes its configured URL and authentication credentials to the fetcher.
- The fetcher places bearer or basic credentials in the Authorization header.
- On a redirect, the fetcher follows the response-provided Location and recursively reuses the same credentials without checking the destination origin.
Evidence against
- Remote code fetching is an explicit cloud-library feature, and the service loads only libraries configured as enabled.
- The credential leak requires an authenticated remote fetch and a cross-origin redirect; the package does not hard-code a collector host.
