Prototype Pollution in lodash
Versions of `lodash` before 4.17.12 are vulnerable to Prototype Pollution. The function `defaultsDeep` allows 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 4.17.12 or later.
