      "value": "Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 4.2.7, 4.1.15, 4.0.15, and 3.5.19, when fetching remote statuses, Mastodon doesn't check that the response from the remote server has a `Content-Type` header value of the Activity Streams media type, which allows a threat actor to upload a crafted Activity Streams document to a remote server and make a Mastodon server fetch it, if the remote server accepts arbitrary user uploads. The vulnerability allows a threat actor to impersonate an account on a remote server that satisfies all of the following properties: allows the attacker to register an account; accepts arbitrary user-uploaded documents and places them on the same domain as the ActivityPub actors; and serves user-uploaded document in response to requests with an `Accept` header value of the Activity Streams media type. Versions 4.2.7, 4.1.15, 4.0.15, and 3.5.19 contain a fix for this issue."

Antes de las versiones 4.2.7, 4.1.15, 4.0.15 y 3.5.19, al recuperar estados remotos, Mastodon no verifica que la respuesta del servidor remoto tenga un valor de encabezado \"Tipo de contenido\" de los flujos de actividad. tipo de medio, que permite a un actor de amenazas cargar un documento de Activity Streams manipulado a un servidor remoto y hacer que un servidor Mastodon lo recupere, si el servidor remoto acepta cargas arbitrarias de usuarios. La vulnerabilidad permite a un actor de amenazas hacerse pasar por una cuenta en un servidor remoto que cumple con todas las siguientes propiedades: permite al atacante registrar una cuenta; acepta documentos arbitrarios subidos por usuarios y los coloca en el mismo dominio que los actores de ActivityPub; y proporciona documentos subidos por el usuario en respuesta a solicitudes con un valor de encabezado \"Aceptar\" del tipo de medio Activity Streams. Las versiones 4.2.7, 4.1.15, 4.0.15 y 3.5.19 contienen una soluci\u00f3n para este problema."
