A vulnerability in OpenCode, an AI coding agent, allowed untrusted MCP servers to execute commands on developer machines via a malicious OAuth sign-in process. This issue, reported by Pillar Security and affecting versions on Windows and WSL, highlights the risks of integrating remote MCP servers, which can act as command runners, LLM input providers, and credential holders. The vulnerability, rated 9.8/10 and lacking a CVE, underscores the need for robust inventory management beyond CVE feeds for developer tools. Additionally, OX Security identified systemic issues with STDIO transport in MCP implementations, where commands are run without proper sanitization, impacting tools like LiteLLM, LangFlow, and Flowise.
