Summary
Misskey is an open source, federated social media platform. 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.

A partir de la versi\u00f3n 12.31.0 y anteriores a la 2025.4.1, la falta de validaci\u00f3n en `Mk:api` permite que c\u00f3digo AiScript malicioso acceda a endpoints adicionales a los que no est\u00e1 dise\u00f1ado. Esta falta de validaci\u00f3n permite que el c\u00f3digo AiScript malicioso anteponga `../` a una URL para salir del directorio `/api`, lo que permite realizar solicitudes a otros endpoints, como `/files`, `/url` y `/proxy`. La versi\u00f3n 2025.4.1 soluciona el problema."
