混淆副官漏洞暴露 MCP 服务器的权限提升风险

混淆副官漏洞是消息队列协议 (MCP) 服务器中的一个安全缺陷,服务器会在未验证调用者授权的情况下转发身份验证令牌。这可能允许攻击者使用本应属于一个服务的令牌来获得对另一个服务的未经授权的访问。该问题源于库使得令牌传递过于容易,以及令牌缺乏严格的受众验证。建议开发人员验证令牌受众,针对最终用户授权每次调用,为下游调用使用单独的凭据,并确保全面的日志记录以防止权限提升。 AI

    <p>Here is a failure that does not look like a bug in code review, passes every test you wrote, and quietly hands an attacker your privileges. It is called the confused deputy, and it is the reason "just forward the token" is one of the most expensive shortcuts you can take in an…
