I believe the word is "Meh.". This is one of the expected use-cases for
CacheMgr. ie how the new access methods are designed to be used.

Strictly speaking its anyone who can access those reports. You just have
one less layer of protection than default installs use.

"public" means there is no report-specific password set by
cachemgr_passwd directive required to access it. The only control will
be the http_access rules you configure.

You create a urlpath_regex ACL to match regular (not squidclient or
cachemgr.cgi) requests for the reports like so:

 acl foo urlpath_regex \

Authentication can be applied in combination with that to do whatever
reports you want authenticated. Also group limitations, external ACL,
specific src IPs, etc..
