# XSS Armazenado em um href de Âncora com Aspas Codificadas

### XSS armazenado no atributo href de âncora com aspas duplas codificadas em HTML

Este laboratório contém uma vulnerabilidade de XSS armazenada no recurso de comentários. Aspas duplas no `href` atributo são codificadas em HTML ("), o que afeta como injetar a carga útil.

Um comentário salvo pode controlar o `href` atributo do nome do autor na seção de comentários; o atributo é retornado como uma âncora, como `<a href="...">`, e as aspas duplas são codificadas, mas o URI da âncora continua utilizável.

Envie um comentário para que, quando o nome do autor for clicado, um `alert()` será executado no navegador do visitante.

Use um URI JavaScript no comentário `href`, por exemplo

```javascript
javascript:alert(document.cookie)
```

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hacking-notes.jord4n.pro/pt-br/web/xss/stored-xss-in-anchor-href-with-encoded-quotes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
