A weakness has been identified in antv layout 2.0.0. This impacts the function setNestedValue in the library lib/util/object.js. Executing a manipulation of the argument path can lead to improperly controlled modification of object prototype attributes. The attack can be launched remotely. The project was informed of the problem early through an issue report but has not responded yet.
