  1) Certain input related to dynamic fields is not properly sanitised
  before being returned to the user. This can be exploited to execute
  arbitrary HTML and script code in a user's browser session in context
  of an affected site.

  2) The application allows users to perform certain actions via HTTP
  requests via iframes without performing any validity checks to verify
  the requests. This can be exploited to perform certain unspecified
  actions by tricking a user into e.g. clicking a specially crafted link
  via clickjacking.");
