What happened

AutoJack is a demonstrated exploit chain where a single malicious webpage can cause remote code execution on the host running an AI browsing agent. The attack abuses trust in localhost, missing or weak authentication, and unsafe parameter handling in AutoGen Studio’s MCP WebSocket to trigger arbitrary process execution on the host. The research highlights a systemic risk: when agents browse untrusted content and can access local services, traditional localhost-based protections and assumptions fail, enabling host compromise.
