By default, a codespace can only access the repository where it was created. When you enable access and security for a repository owned by your organization, any codespaces that are created for that repository will also have read and write permissions to all other repositories the organization owns and the codespace creator has permissions to access. If you want to restrict the repositories a codespace can access, you can limit to it to either the repository where the codespace was created, or to specific repositories. You should only enable access and security for repositories you trust.
To manage which users in your organization can use Codespaces, see "Managing user permissions for your organization."
