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."}, {"lang": "es", "value": "Mastodon es un servidor de red social gratuito y de c\u00f3digo abierto basado en ActivityPub.

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.
