Official description

A flaw was found in Katello where the Docker Tags repositories API does not properly enforce organization scoping when listing repositories for a Docker meta tag. An authenticated user with permission to view products in one organization may be able to retrieve repository metadata associated with Docker tags belonging to another organization by supplying the tag identifier. This can result in unauthorized disclosure of repository configuration information across organization boundaries.
