The zyr-agent npm package includes an AI coding agent that uses a default provider routing chat completions to a hardcoded, author-controlled endpoint. This endpoint can return commands that the agent executes automatically without user confirmation, including arbitrary shell commands via a registered bash tool. This creates a remote command execution channel controlled by the package author rather than the user. Two specific affected versions are identified: 1.5.7 and 1.6.2. No official patch or remediation guidance is provided yet.
