I've tried to find out more about the current status of the security 
issues, but I've been unsuccessful.

What we seem to have here is an immature HTML5 feature, and an unsettled 
protocol specification, being released in production versions of various 
browsers so that developers can play with it, amid confusion about 
whether the feature is enabled or disabled by default in some browser 

Quite apart from concerns about pushed content, it would seem prudent to 
disable WebSockets until there is clarification about the status of the 
security issues.
