Prototype Pollution in nuysoft/mock
Version 1.1.0 of mockjs is vulnerable to prototype pollution; Util.extend do not check if the attribute resolves to the object prototype.
By adding or modifying attributes of an object prototype, it is possible to create attributes that exist on every object, or replace critical attributes with malicious ones. This can be problematic if the software depends on existence or non-existence of certain attributes, or uses pre-defined attributes of object prototype (such as hasOwnProperty, toString or valueOf).
