Description
An authorization flaw in the aggregation and view-definition handling of sharded deployments may allow a user holding only basic read-write privileges on a single database to define a view whose underlying processing is not fully subjected to privilege checking. Reading that view may result in unintended access to data belonging to other databases held on the same shard.
