The active Google login and token-refresh paths send service credentials to a publisher-selected default recipient without recipient-specific consent. This is concrete credential exposure, so the package should be blocked.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

A user initiates Google login, completes OAuth, or the server refreshes a saved Google session.

Impact

The worker receives credentials that can grant access under the requested Google Drive and account scopes.

Mechanism

The server posts the callback code and saved refresh token to the default worker endpoint, then stores the returned tokens.

Attack narrative

The CLI starts the bundled server, whose default Google auth worker is hosted on the publisher-associated domain. During Google login, the callback sends the authorization code there; refresh requests send the saved refresh token to that same host. The source shows no recipient-specific consent for this transfer. The worker receives credentials associated with Google Drive and account scopes.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The package launches server/dist/server.js through its CLI entry point.
The server defaults Google OAuth to a publisher-selected worker host.
On Google OAuth callback, the server sends the authorization code to that worker and saves the returned tokens.
When refreshing Google credentials, the server sends the saved refresh token to the same worker.
The callback is reached during Google login, and the requested scopes include Google Drive access.

Evidence against

The package supports configuring a custom Google auth worker URL, but the publisher-selected default remains active without that override.
