22.3.0
^^^^^^


Security Issues
***************

* A vulnerability in the console proxies (novnc, serial, spice) that
  allowed open redirection has been patched. The novnc, serial, and
  spice console proxies are implemented as websockify servers and the
  request handler inherits from the python standard
  SimpleHTTPRequestHandler. There is a known issue in the
  SimpleHTTPRequestHandler which allows open redirects by way of URLs
  in the following format:

     http://vncproxy.my.domain.com//example.com/%2F..

  which if visited, will redirect a user to example.com.

  The novnc, serial, and spice console proxies will now reject
  requests that pass a redirection URL beginning with "//" with a 400
  Bad Request.
