About base permissions for an organization
You can set base permissions that apply to all members of an organization when accessing any of the organization's repositories. Base permissions do not apply to outside collaborators.
If someone with admin access to an organization's repository grants a member a higher level of access for the repository, the higher level of access overrides the base permission.
If you've created a custom repository role with an inherited role that is lower access than your organization's base permissions, any members assigned to that role will default to the organization's base permissions rather than the inherited role. For more information, see Managing custom repository roles for an organization.
Note
- All changes to base permissions will affect both new and existing members.
- When you change base permissions for an organization, permissions for private forks are not automatically updated.
