### Muse，Meta极其特权的AI助手，存在严重的0-day漏洞

Meta的AI助手Muse被发现存在一个关键的零日漏洞，带来了显著的安全风险。该缺陷允许本地应用程序和终端命令对助手进行不受限制的控制，这与Meta最近关于产品隐私和安全的保证相矛盾。在Muse发布后不久发现这一漏洞，引发了对其安全措施稳健性的质疑，以及对用户数据保护的影响。

**要点：**

- Muse的零日漏洞削弱了其宣传的安全特性。
- 该缺陷允许未经授权的访问，给用户数据带来风险。
- Meta快速推出Muse引发了对全面测试的担忧。

**为什么重要：** 在像Muse这样高调的AI助手中发现严重漏洞，突显了确保AI技术安全的持续挑战，尤其是随着它们越来越多地融入日常生活。此事件提醒我们在产品发布前进行严格安全测试的重要性。
