CVE-2026-6130Public exploitNetwork attack vector

Command execution via unvalidated MCP server configuration

Published Apr 12, 2026 · Updated Apr 12, 2026

OS command injection in Chatbox 1.20.0 and earlier allows remote attackers to execute commands through malicious MCP server configurations. StdioClientTransport passes unvalidated command, args, and env values from imported or deep-linked server data to a child-process transport. A user must save a crafted deep link configuration or import a crafted file; an enabled server then runs with the desktop user's privileges during startup.
