MCP配置缺陷导致未经信任的代码执行后门

MCP(模型通信协议)配置中发现了一个安全漏洞,其中`.mcp.json`文件可充当后门,允许未经信任的代码执行。该配置文件因其看似简单的配置而被忽视,但它可能授予第三方组织访问敏感凭证和模型指令流的权限。现有安全工具(如CodeQL和Dependabot)不会扫描这些配置文件,导致它们未被审查并容易被利用,从而产生了此漏洞。作者详细介绍了完整的攻击链,并提出了应对这些风险的缓解策略。 AI

    <p>Everyone has probably tried adding an MCP server and knows that it only takes a few lines of JSON. And those few lines grant a third-party organization permission to execute code! Just imagine that your credentials and the recording stream are passed directly into the model’s …
