Description Andrej Nemec 2016-06-07 07:58:31 UTC 
A default cipher key is used for the "remember me" feature when not
explicitly configured.  A request that included a specially crafted request
parameter could be used to execute arbitrary code or access content that
would otherwise be protected by a security constraint.
