Starting in version 12.31.0 and prior to version 2025.4.1, missing validation in `Mk:api` allows malicious AiScript code to access additional endpoints that it isn't designed to have access to. The missing validation allows malicious AiScript code to prefix a URL with `../` to step out of the `/api` directory, thereby being able to make requests to other endpoints, such as `/files`, `/url`, and `/proxy`. Version 2025.4.1 fixes the issue."},{"lang":"es","value":"Misskey es una plataforma de redes sociales federada de código abierto. A partir de la versión 12.31.0 y anteriores a la 2025.4.1, la falta de validación en `Mk:api` permite que código AiScript malicioso acceda a endpoints adicionales a los que no está diseñado. Esta falta de validación permite que el código AiScript malicioso anteponga `../` a una URL para salir del directorio `/api`, lo que permite realizar solicitudes a otros endpoints, como `/files`, `/url` y `/proxy`.
