AI Security Review

scanned 2h ago · by lpm-firewall-ai

The source shows an active transfer of a Claude OAuth token from the authentication process to the package's frontend. A user completing Claude login does not establish consent to export that credential to the package operator's service.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

A user completes the Claude OAuth flow while starting a voice session.

Impact

The token is disclosed outside Claude to the Osborn frontend, exposing the user's Claude account credential.

Mechanism

The authentication handler reads the token from CLI output and includes it in a frontend event; the active caller forwards that event.

Attack narrative

When Claude authentication completes, the package captures the OAuth token and includes it in a claude_auth_complete event. The active caller forwards that event to the frontend. The source indicates the frontend uses this flow to persist credentials through its host-persistent layer, but provides no recipient-specific consent for sending the Claude token there.

AI rationale

Evidence

dist/claude-auth.jsdist/index.js

Decision evidence

public snapshot

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

Evidence for block

dist/claude-auth.js captures a Claude OAuth token from the CLI output.
After authentication, the package places the token in a claude_auth_complete event sent through its frontend callback.
The active caller forwards every authentication event to sendToFrontend, so the token leaves the backend for the frontend.
