本文记录了针对已归档 Python 包 langchain-experimental 的代码审计过程。在该包的 PythonAstREPLTool 组件中,发现其对大模型(LLM)输出内容的过滤机制较弱,且直接使用 exec/eval 执行输入。结合平台判定与最新下载量数据,本文客观分析了该组件在现阶段(已停止维护)存在的安全风险及修复建议。

本文针对 xAI 官方开源组件 xai-grok-agent 进行了深度的静态源码审计。研究发现,系统在加载本地配置文件(如 AGENTS.md)时,存在未经隔离的直接字符串拼接(CWE-1427),并在拼接后附加了强制执行指令。攻击者可通过供应链投毒(恶意开源仓库),实现对开发者本地 AI Agent 的持久化上下文劫持(OWASP ASI06)。文章披露了从文件读取到提示词拼接的完整攻击链,并

它不是内存安全漏洞,也不是逻辑越权。它的本质是:地址解析层中存在三条相互独立的超线性(近二次)性能路径与一个参数上限触发的异常路径,而地址解析在 Node.js 的单线程事件循环上同步执行。
