[Cppcms-users] empty action in POST a potential vulnerability ?

 I was just reading on a blog post that an empty action in post could
in theory trigger a bypassing of CSRF. Details here:

 Is this true for cppcms ? I've noticed that the wiki code does indeed
use empty actions in post forms. It would also seem that html5 doesn't
allow this anymore and that a non empty action must be specified.

 Thanks.
