We are tracking this at foswiki.org/Tasks/Item11498.
To mitigate the impact of trivial JS injection as demonstrated by Sony, public Foswiki sites which allow unmoderated user registration should customize their NewUserTemplate to restrict VIEW/CHANGE access on those new user profile topics, and also check to see if all webs (including Sandbox) have ACLs set to deny new users CHANGE permission everywhere in the wiki.
Typically, public Foswiki installations grant CHANGE permission to groups, and then add trusted users to those groups.
