In affected versions missing validation in `ApRequestService.signedGet` and `HttpRequestService.getActivityJson` allows an attacker to create fake user profiles and forged notes. The spoofed users will appear to be from a different instance than the one where they actually exist, and the forged notes will appear to be posted by a different user. Vulnerable Misskey instances will accept the spoofed objects as valid, allowing an attacker to impersonate other users and instances. The attacker retains full control of the spoofed user / note and can interact like a real account. This issue has been addressed in version 2024.11.0-alpha.3. Users are advised to upgrade. There are no known workarounds for this vulnerability."}, {"lang": "es", "value": "Misskey es una plataforma de redes sociales federada de c\u00f3digo abierto. En las versiones afectadas, la falta de validaci\u00f3n en `ApRequestService.signedGet` y `HttpRequestService.getActivityJson` permite a un atacante crear perfiles de usuario falsos y notas falsificadas. Los usuarios falsificados parecer\u00e1n ser de una instancia diferente a la que realmente existen, y las notas falsificadas parecer\u00e1n haber sido publicadas por un usuario diferente. Las instancias vulnerables de Misskey aceptar\u00e1n los objetos falsificados como v\u00e1lidos, lo que permite a un atacante hacerse pasar por otros usuarios e instancias. El atacante conserva el control total del usuario/nota falsificados y puede interactuar como una cuenta real. Este problema se ha solucionado en la versi\u00f3n 2024.11.0-alpha.3.
