Microsoft has detailed a security vulnerability in AutoGen Studio, an exploit chain named AutoJack, where a browsing agent could execute arbitrary code on the host machine. The exploit leveraged an untrusted web page to interact with a local MCP WebSocket, bypassing security boundaries. While Microsoft states the vulnerability was patched upstream and never released in a public PyPI version of AutoGen Studio, they emphasize the broader lesson for developers: agent frameworks combining browsing, local tools, and execution capabilities require robust isolation and authentication to prevent such risks.
