Without a rate limit on the POST /uploads endpoint, it makes it easier for an attacker to carry out a DoS attack on the server since creating an upload can be a resource intensive process. Do note that the impact varies from site to site as various site settings like `max_image_size_kb`, `max_attachment_size_kb` and `max_image_megapixels` will determine the amount of resources used when creating an upload. The issue is patched in the latest stable, beta and tests-passed version of Discourse. Users are advised to upgrade. Users unable to upgrade should reduce `max_image_size_kb`, `max_attachment_size_kb` and `max_image_megapixels` as smaller uploads require less resources to process. Alternatively, `client_max_body_size` can be reduced in Nginx to prevent large uploads from reaching the server."}, {"lang": "es", "value": "Discourse es una plataforma de c\u00f3digo abierto para el debate comunitario. Sin un l\u00edmite de velocidad en el endpoint POST /uploads, a un atacante le resulta m\u00e1s f\u00e1cil llevar a cabo un ataque DoS en el servidor, ya que crear una carga puede ser un proceso que consume muchos recursos. Tenga en cuenta que el impacto var\u00eda de un sitio a otro, ya que varias configuraciones del sitio, como `max_image_size_kb`, `max_attachment_size_kb` y `max_image_megapixels`, determinar\u00e1n la cantidad de recursos utilizados al crear una carga. El problema est\u00e1 solucionado en la \u00faltima versi\u00f3n estable, beta y probada de Discourse. Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar deben reducir `max_image_size_kb`, `max_attachment_size_kb` y `max_image_megapixels` ya que las cargas m\u00e1s peque\u00f1as requieren menos recursos para procesar.
