      "value": "Dendrite is a Matrix homeserver written in Go. In affected versions events retrieved from a remote homeserver using the `/get_missing_events` path did not have their signatures verified correctly. This could potentially allow a remote homeserver to provide invalid/modified events to Dendrite via this endpoint. Note that this does not apply to events retrieved through other endpoints (e.g. `/event`, `/state`) as they have been correctly verified. Homeservers that have federation disabled are not vulnerable. The problem has been fixed in Dendrite 0.9.8. Users are advised to upgrade. There are no known workarounds for this issue."

      "value": "Dendrite es un servidor dom\u00e9stico de Matrix escrito en Go. En las versiones afectadas, los eventos recuperados de un servidor dom\u00e9stico remoto usando la ruta \"/get_missing_events\" no presentaban sus firmas verificadas correctamente. Esto podr\u00eda permitir que un servidor dom\u00e9stico remoto proporcionara eventos no v\u00e1lidos/modificados a Dendrite por medio de este endpoint. Ten en cuenta que esto no es aplicado a eventos recuperados mediante otros endpoints (por ejemplo, \"/event\", \"/state\") ya que han sido correctamente verificados. Los servidores dom\u00e9sticos que presentan la federaci\u00f3n deshabilitada no son vulnerables. El problema ha sido corregido en Dendrite versi\u00f3n 0.9.8. Es recomendado a usuarios actualizar. No se presentan mitigaciones conocidas para este problema"
