# HTML 上下文中的存储型 XSS，未编码

HTML 上下文中的存储型 XSS，未编码笔记，适用于 PortSwigger Web Security Academy 实验室，包括利用流程、载荷测试、Burp Suite 验证和修复上下文。

### 未进行任何编码而存储到 HTML 上下文中的 XSS

这是一个存储在博客评论功能中的跨站脚本漏洞。在评论表单中输入的数据会在未编码的情况下插入到 HTML 中。

#### 实验目标

提交一个会执行的评论 `alert()` 当帖子页面显示时（通过导致访客弹窗来解决实验）。

```javascript
<script>alert("评论")</script>
<script>alert("姓名")</script>
<script>alert("电子邮件")</script>
<script>alert("网站")</script>
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/zh/web/xss/stored-xss-in-html-context-without-encoding.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
