Descriptions
Fedify is a TypeScript library for building federated server apps powered by ActivityPub and other standards. At present, when Fedify needs to retrieve an object or activity from a remote activitypub server, it makes a HTTP request to the `@id` or other resources present within the activity it has received from the web. This activity could reference an `@id` that points to an internal IP address, allowing an attacker to send request to resources internal to the fedify server's network. This applies to not just resolution of documents containing activities or objects, but also to media URLs as well. Specifically this is a Server Side Request Forgery attack. Users should upgrade to Fedify version 0.9.2, 0.10.1, or 0.11.1 to receive a patch for this issue.
Fedify es una biblioteca de TypeScript para crear aplicaciones de servidor federado impulsadas por ActivityPub y otros estándares. En la actualidad, cuando Fedify necesita recuperar un objeto o actividad de un servidor de actividad remoto, realiza una solicitud HTTP al `@id` u otros recursos presentes dentro de la actividad que ha recibido de la web. Esta actividad podría hacer referencia a un `@id` que apunta a una dirección IP interna, permitiendo a un atacante enviar solicitudes a recursos internos de la red del servidor de Fedify. Esto se aplica no sólo a la resolución de documentos que contienen actividades u objetos, sino también a las URL de medios. Específicamente, se trata de un ataque de Server Side Request Forgery. Los usuarios deben actualizar a Fedify versión 0.9.2, 0.10.1 o 0.11.1 para recibir un parche para este problema.
