Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not
properly verifying restore privileges when restoring a file. The restore
capability of Nextcloud/ownCloud was not verifying whether a user has only
read-only access to a share. Thus a user with read-only access was able to
restore old versions.
