Yes. By accessing the cachemgr.cgi that you have given permission to
access the cache info object, a user can bypass the ACL protection you
have placed on people accessing the cache object from anywhere else.

You can avoid this by protecting cachemgr.cgi using your web server
security, or change the cgi to something else (security by obscurity).

Ideally the cachemgr.cgi should have a builtin check that compares
HTTP_HOST with the ACL on Squid.
