osborn@0.9.183
Voice AI coding assistant - local agent that connects to Osborn frontend
AI Security Review
scanned 1mo ago · by lpm-firewall-aiSource inspection confirms an unauthenticated runtime editor path, remote script execution, and OAuth-token forwarding. There is no automatic registry-install lifecycle hook or self-dependency chain, so this is a critical vulnerability rather than malicious package behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A request to GET /editor or completion of the Claude authentication flow.
Impact
An unauthorised requester may obtain an editor session for the service workspace; a compromised installer or frontend callback could execute code or receive the OAuth token.
Mechanism
Unauthenticated editor startup, remote shell installer, and OAuth-token forwarding.
AI rationale
Source inspection confirms an unauthenticated runtime editor path, remote script execution, and OAuth-token forwarding. There is no automatic registry-install lifecycle hook or self-dependency chain, so this is a critical vulnerability rather than malicious package behavior.
Evidence
dist/index.jsdist/claude-auth.js/workspace~/.claude/.oauth-token~/.claude/.credentials.json
Network endpoints1
code-server.dev/install.sh
Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Critical Vulnerability with low false-positive risk.
Evidence for warning
- The public editor route explicitly has no authentication gate and starts the editor service on request.
- If code-server is absent, that reachable route downloads and pipes a remote script into a shell.
- The Claude OAuth completion event forwards the active OAuth token to the frontend callback.
Evidence against
- The manifest has no preinstall, install, or postinstall hook; its only lifecycle entry is prepublishOnly.
- The risky behavior belongs to the stated remote coding-agent service rather than concealed install-time malware.
