Never had these issues at all if you set up vhosts correctly.
But agree we tend to have 2 vhosts for the domain
* vhost 1 is the real vhost and handle requests
* vhost 2 contains all the redirects from other domain names to the canonical one
The only ServerAlias lines in vhost 1 are for development URLs which are run on different servers
But we also don't expose our wordpress - but use a mirroring script to serve the site as predominantly static {takes careful design to do this!}

Subject: Re: site compromised and httpd log analysis [EXT]
ok may or may not be related but i found i had to lock php, wordpress etc down heavely in apache
especially if you are using vhosts
i found one authorized site could talk to another without making things more strict
yes its a pain to have one vhost per site but its the only way to fully isolate one from the other
if someone executes stuff it stays within their working directory
example (shows http alias etc - note the directory directives - i use a database --> script generator so its not too inconvient.) :
<VirtualHost *:80>
