Prototype Pollution in lodash.merge

Versions of lodash.merge before 4.6.2 are vulnerable to prototype pollution. The function merge may allow a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.

Recommendation

Update to version 4.6.2 or later.
