Users not members of our team make changes to our codebase, how?

[Kerry Carlyle]

Hi, we have just had someone who is not part of our organization, and not a member of the repository make changes to our code, how is this possible?

The repository is marked private.

Hi, @Kerry Carlyle! 

Thank you for reaching out to Atlassian Community!

Could you please share with me where you see that a person who is not a member of this repo made changes to the code? The reason I’m asking this is that this could be due to a local git configuration. Some users who are members of the repo may have a different Author name in Git. This is a git expected behavior and Bitbucket UI would show the Author name as provided from the git config. 

The users can check this git configuration by running the following command in their local machine:

git config --list 

This will show the username and email that they have set.

Looking forward to hearing from you.

Kind regards,
Caroline
