There are two parts to configuring the access controls on the cache
manager, the first is to tell squid which cache managers it should
listen to this you do in squid.conf. You've told it to listen to any
cachemgr in and

The next step is to tell the web servers running cachemgr.cgi whom
they will talk to. It looks like your's is wide open so it will let
anybody connect. Since the cgi process is connecting from within one
of the allowed domains squid grants access. Tell your web server not
to do this and you've got it made. Something like this for Apache:

        # In httpd.conf
        ScriptAlias /squid-status /var/www/squid/bin/cachemgr.cgi
        # In access.conf
        <Location /squid-status>
                <Limit GET>
                        order deny,allow
                        deny from all
                        allow from
