Exposed GitLab project email addresses let attackers push code
Private GitLab email addresses that can be used to push code or issues into projects are being publicly exposed in documentation like READMEs and contributor guides. This creates an opening for attackers to interact with private project infrastructure in ways that were not intended.
Why this matters: Most people assume a project's code repository is protected by passwords and access controls. This is a different kind of problem. A single email address, posted in plain sight, can let an outsider inject content directly into a private project. Developers who post these addresses to make contribution easier are quietly handing strangers a door. Teams using GitLab should check what they are publishing in their own documentation before an attacker does it for them.
