N1QL: password protected bucket: Able to access password protected bucket without username,password using curl command and cbq shell

Steps to repro:
1. Download 4.5.0-2023 on macos, I downloaded on my machine.Yosemite 10.10.5 version.
2. select beer-sample during setup of couchbase.
3. We see 2 unprotected buckets in UI: default and beer-sample.
4. create primary index on beer-sample through query tab.

Go to path: ~Downloads/couchbase-server-enterprise_4/Couchbase Server.app/Contents/Resources/couchbase-core/bin on your machine

5. Able to access both buckets through shell without username,password which is correct.
6. Edit properties of beer-sample and enter a password:pass1
7. Still able to do select * from beer-sample from cbq without any creds.
8. Tried same through curl command, get this output:

prernamanaktala@couchbases-MacBook-Pro bin $ curl -v http://127.0.0.1:8093/query/service -d 'statement=select * from `beer-sample` limit 1'
