    Summary: Prototype Pollution in lodash

    Details: Versions of `lodash` before 4.17.5 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 `__proto__` causing the addition or modification of an existing property that will exist on all objects. ## Recommendation Update to version 4.17.5 or later.
