# ID de usuario controlado por parámetro
### ID de usuario controlado por un parámetro de solicitud
Este laboratorio presenta un **escalada horizontal de privilegios** un problema en la página de la cuenta de usuario. / Para resolver el laboratorio, necesitas recuperar la **clave API de usuario carlos** y enviarla como solución. / Puedes conectarte con las siguientes credenciales: **wiener:peter**.
En nuestro propio panel de usuario (el de wiener), observamos que el ID de la cuenta se transmite en un parámetro de URL.
Al cambiar este parámetro y reemplazar nuestro ID por carlos, por ejemplo:
```bash
/my-account?id=carlos
```
La página entonces muestra la información de la cuenta de carlos, permitiéndonos recuperar su \*\*clave API\*\*.

## 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/es/web/access-control/user-id-controlled-by-parameter.md?ask=&goal=
```
`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.
