Versions of lodash before 4.17.11 are vulnerable to prototype pollution.
The vulnerable functions are ‘defaultsDeep’, ‘merge’, and ‘mergeWith’ which 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 4.17.11 or later.
