Does that mean, an update of a 5.2.0 installation to 5.2.1 will not fix the permission problem?For sites created with the affected 5.2.0 packages, an automated solution updating the permissions of affected files and folders will be shipped with the next regular 5.2.x release. Site owners can either wait for that release or update the permissions manually.
Does that mean a version like 5.2.2 will fix a 5.2.0 installation?
