从 Burp 扩展研究出发，对 Yakit 插件机制进行黑盒验证，并进一步讨论安全工具扩展生态中的代码执行与供应链风险

本文记录一次基于源码包的 Java Web 系统安全审计过程。 我没有直接进入黑盒测试，而是按"web.xml 路由 → CFR 反编译 → 数据流追踪"的顺序先建立攻击面全景，再以线上实测对审计结论分级验证。 审计阶段定位到防注入过滤器被注释、权限判断短路、.do 反射链、DAO 层全量Statement 拼接、明文密码导出、任意文件下载等多类缺陷，并逐一给出反编译原文与文件行号；验证阶段实测确

初步认识 k8s 与 k8s 安全基础

面向若依生态的专项漏洞扫描器实现解析：三态判定降低误报、AI 生成 POC 自验证回灌、nuclei 模板兼容，附靶场实战验证与真实 POC 代码。

CVE-2026-74610 是 Linux 内核 ktls 子系统新近披露的漏洞，因散射链表处理错误导致越界。本文主要分析该漏洞原理，并给出可用于验证漏洞的poc

本文是对 XSS（Cross-Site Scripting，跨站脚本攻击）的二次回顾与学习总结，主要围绕 XSS 的基本原理、反射型/存储型/DOM 型分类、常见危害以及漏洞探测展开。在此基础上，重点整理了 XSS 中常见的过滤绕过思路，包括双写、大小写、空格、闭合、注释、HTML 实体、事件处理器、伪协议、SVG 等技巧，并结合具体代码分析其产生原因与适用场景。文章最后以 XSS-labs 为主
