"The Object module in Liferay Portal and Liferay DXP does properly isolate objects in difference virtual instances, 
which allows remote authenticated users in one virtual instance to view objects in a different virtual instance via 
OAuth 2 scope administration page.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
