osborn@0.9.190

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

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

There is no install-time trigger or hidden endpoint, but the package has high-impact runtime data-transfer and remote-install capabilities. The full-session retrieval path makes the privacy boundary insufficiently constrained.

Static reason

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

Trigger

A user asks the running assistant a fast-brain question or sends the start_ide command.

Impact

Private conversation and tool-output data may leave the machine; a compromised installer endpoint could execute code.

Mechanism

Session-content upload and remote shell installer execution.

AI rationale

Evidence

dist/pipeline-fastbrain.jsdist/index.js~/.claude/projects/{slug}/osb/{sessionId}/search-index.txt

Network endpoints2

openrouter.aicode-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 fast-brain feature sends user questions, session history, and model tool results to OpenRouter.
Its search tool returns full untruncated session content, which can include command output and sensitive material.
A runtime IDE action downloads and pipes a remote installer script into a shell.

Evidence against

package.json has no install, preinstall, or postinstall hook; its only lifecycle script is prepublishOnly.
The network and execution paths are activated at runtime by assistant or IDE use, not package installation.
