The flaw chains three weaknesses: a localhost WebSocket trust issue, missing authentication on MCP API routes, and unsanitized base64-encoded parameters passed to process-launching code. Together, these allow a malicious webpage visited by a developer's AI agent to execute arbitrary commands on the host machine. The affected code never shipped in a PyPI release — only developers building directly from the GitHub main branch during a brief window were exposed. Microsoft has patched the issue and recommends running AutoGen Studio in isolated, sandboxed environments with low-privilege accounts. ## Full article daily.dev links to this article rather than hosting it.
