# エンコードされた山括弧、エンコードされた二重引用符、エスケープされたアポストロフィを含むJavaScript文字列内のXSS
PortSwigger Web Security Academy のラボ向けメモ。エンコードされた山括弧、エンコードされた二重引用符、エスケープされたアポストロフィを含むJavaScript文字列内のXSSに関するもので、攻撃手順、ペイロードのテスト、
### 山括弧とダブルクォートがHTMLエンコードされ、シングルクォートがエスケープされたJavaScript文字列への反射型XSS
このラボには反射型XSSの脆弱性があります。検索値がJavaScript文字列に挿入されます。 `<`/`>` さらに、ダブルクォートはHTMLエンコードされ、シングルクォートはエスケープされます。目的：JavaScript文字列から抜け出して、呼び出す `alert()`.

# 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/ja/web/xss/xss-in-a-javascript-string-with-encoded-angle-brackets-encoded-double-quotes-and-escaped-apostrophe.md?ask=&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.
