    METR:为什么 AI 推理应当可读且忠实

    METR 发文主张 AI 系统的推理过程应当既「可读」(人类能读懂)又「忠实」(真实反映模型的决策过程),认为这有助于发现 AI 错误、检测隐藏议程、监控欺骗行为和识别能力造假。文章指出 OpenAI、Anthropic、xAI、Google DeepMind 和 DeepSeek 都在过去四个月里发布了推理模型,其当前产出的推理已具价值、值得保留。

    ChatGPT Operator 提示注入攻击实测与防御分析

    Aim Labs 披露 Cursor 经 MCP 自动启动触发远程代码执行漏洞 CurXecute

    Aim Labs 在 Cursor IDE 中发现高危漏洞 CurXecute,可导致完整的远程代码执行,编号 CVE-2025-54135,严重性评级 8.6。攻击路径是:当 Cursor 接入会读取外部内容的 MCP 服务器(如 Slack)时,一条被投毒的提示词就能诱导智能体改写 ~/.cursor/mcp.json;而 Cursor 会立即执行该文件新增的条目,并在用户确认前就写入磁盘,从而以用户权限执行攻击者命令。Cursor 已在 1.3 版本修复,更早版本仍受影响。
