The server sends Google login and refresh credentials to a fixed package-selected external recipient during ordinary authentication. This is a concrete credential disclosure, even though the transfer occurs within a functional login flow.

Static reason

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

Trigger

A user completes Google login or the app refreshes a saved Google session.

Impact

The worker receives material that can be used to obtain or refresh Google access tokens.

Mechanism

The server posts the login authorization code and saved refresh token to the default worker URL, without a recipient-specific consent check.

Attack narrative

The default Google authentication flow routes a login authorization code to a worker selected by the package, then saves the worker response as session tokens. Later, the server sends the saved refresh token to that worker. The user initiates Google login, but the inspected code has no recipient-specific consent check for sending these credentials to the package-selected worker.

Decision evidence

public snapshot

AI called this Malicious at 95.0% confidence as Malware with low false-positive risk.

Evidence for block

The server defaults Google authentication to a package-selected worker.
The normal Google login callback sends its authorization code to that worker and saves the response as tokens.
When access tokens need refreshing, the server sends the saved Google refresh token to the same worker.
The worker path is selected whenever the configured worker URL is present; the package default makes that path active.

Evidence against

The transfer occurs as part of the app’s Google login and token refresh flow, rather than through an install hook.
