      "value": "Weblate is a web based localization tool. In versions prior to 5.17, the translation memory API exposed unintended endpoints, which in turn didn't perform proper access control. This issue has been fixed in version 5.17. If developers are unable to update immediately, they can disable this feature as the CDN add-on is not enabled by default."

      "value": "Weblate es una herramienta de localización basada en web. En versiones anteriores a la 5.17, la API de memoria de traducción expuso puntos finales no intencionados, lo que a su vez no realizaba un control de acceso adecuado. Este problema ha sido solucionado en la versión 5.17. Si los desarrolladores no pueden actualizar inmediatamente, pueden deshabilitar esta característica ya que el complemento CDN no está habilitado por defecto."
