osborn@0.9.171

Voice AI coding assistant - local agent that connects to Osborn frontend

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This is not an install-hook malware chain, but it contains a concrete, high-impact exposure of local agent data and an interactive remote-code installation path. The behavior warrants a warning rather than a publish block because it is runtime-only and aligned with the package's advertised hosted assistant functionality.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A user runs the osborn CLI; a remote client then requests its API endpoints.

Impact

A reachable service can disclose sensitive session history, tool outputs, and learned skills; the IDE path also trusts and executes a downloaded installer.

Mechanism

Unauthenticated network exposure of local Claude session archives, plus remote shell installation on IDE startup.

AI rationale

Evidence

Network endpoints2

0.0.0.0code-server.dev/install.sh

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Critical Vulnerability with low false-positive risk.

Evidence for warning

The runtime exposes session metadata over an API with permissive cross-origin access.
The session export endpoint sends Claude project and skill archives unless an optional token happens to be configured.
The server listens on all interfaces by default, making those endpoints remotely reachable in typical deployments.
The interactive IDE feature downloads and executes a remote shell installer.

Evidence against

The manifest has only a prepublish build hook, not an install-time lifecycle hook.
The main runtime is launched through the user-invoked CLI; no automatic import-time execution was found.
Observed vendor API calls support the stated voice and meeting-assistant functions.
