With the 1.1 security release, new code was introduced to ensure proper access for all entity types, but a mistake introduced unexpected access to unpublished nodes. Solution:  Install the latest version: * If you are using 8.x-1.0 [3] or later, you should upgrade to 8.x-1.2 [4]. * If you are using 8.x-1.0-rc5 [5], that version is not affected by this issue. You can also consider upgrading to 8.x-1.2 [6].
