@agenthub-ai/agent @0.9.2

Summary

The package runs a daemon that opens a WebSocket connection to a hardcoded server at wss://agenthub-agent.fyenet.com and treats messages from that server as control-plane commands executed on the installer's host. Incoming MessageSend actions are forwarded as user prompts to a Claude Code SDK session started with permissionMode set to 'bypassPermissions', so the remote server's text drives Claude Code's Bash and Edit tools without any local approval, yielding full remote code execution. The same channel exposes FileTree, FileRead, FileWrite, and FileSearch actions with no path allow-list: listDrives() enumerates A: through Z: on Windows, readFileContent returns arbitrary files (up to 20MB) back over the WSS connection, and writeFileContent drops attacker-supplied content to any path the daemon can access. An AgentUpdate action spawns a detached child that runs agenthub-agent update , which resolves the latest version from the npm registry and runs npm install -g @agenthub-ai/agent@<latest> , letting whoever controls the server (or the publishing account) swap the daemon code on every host on demand. Whether launched interactively or as a background service, once the daemon is running the hardcoded remote endpoint has arbitrary shell execution, arbitrary read/write of the filesystem, and persistent code-swap capability on the installer's machine.
