Can you see the results of Bitbucket 's private repository build?

When I built a private repository of Bitbucket I prepared for testing, I can see the build result even by a non login user.

Bitbucket Private repository:
Build Result:

Is this a bug?

You can also download it by entering artifacts / containers / 0 etc in the URL fragment.


If you turn off Free and Open Source, it was good!
