If you cannot patch yet, restrict add or edit privileges on group repositories to trusted users only and review permissions granted to anonymous users to ensure they do not have add or edit privileges.
Description
Sonatype Nexus Repository 3 has an authorization bypass vulnerability where a user with valid credentials and add or edit privileges on a group repository can add a repository they are not authorized to access. This allows the user to read content from that unauthorized repository via the group repository. Anonymous users can only exploit this if explicitly granted the necessary privileges by an administrator.
