osborn@0.9.155

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

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The code contains a serious runtime data-exposure and remote-installer capability, but source inspection found no automatic install-time execution or covert exfiltration chain. It is suspicious dangerous functionality rather than proven malware.

Static reason

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

Trigger

A user runs the osborn CLI and the API port is reachable by another party.

Impact

An attacker able to reach the API port may obtain conversation records, tool outputs, and installed skills; a separate user-driven IDE feature executes a downloaded shell installer.

Mechanism

Unauthenticated export of local Claude session archives over a network listener.

AI rationale

Evidence

dist/index.jsdist/session-access.js~/.claude/projects~/.claude/skills

Network endpoints2

0.0.0.0code-server.dev

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The package provides a CLI that launches its runtime with the caller's environment.
The runtime exposes an archive of Claude projects and skills; authentication is skipped when its optional sync token is unset.
The API server listens on all interfaces by default, making that export reachable beyond localhost if its port is exposed.
Session utilities resolve and read Claude data from the user's home configuration directory.
The runtime can download and execute a remote code-server installer through a shell.

Evidence against

The manifest has only a prepublish hook, not an install-time lifecycle hook.
The risky behavior requires an explicit CLI/runtime launch; no automatic registry-install execution was found.
The reviewed network calls are aligned with the voice, meeting, and IDE features rather than a hidden collector.
