A security vulnerability has been identified in the MCP STDIO transport mechanism, which allows AI agents to connect to local tools and services. OX Security's research indicates that if an attacker can control input to the command launched by MCP, they may be able to execute arbitrary code on the host machine. This issue stems from the design where commands are executed before the validity of the MCP server is confirmed, creating a potential attack surface through direct command injection, allowlist bypasses, and IDE prompt injection.
