The new privileges needed are: cluster:manage, cluster:write, data:manage and 
data:write. A user needs to have all these privilege satisfied in order to 

> function "deploy" only requires DATA:MANAGE privilege, but a malicious user 
> can write a function to change the securityManager and then execute anything

>             Fix For: 1.1.0
> A simple function would do the following:
> SecurityUtils.setSecurityManager(null);
> This would jeopardize all the security checks afterwards and let user do 
> pretty much everything.
> We should either sandbox the function execution or have deploy require ALL 
> permissions.
