Lodash has Prototype Pollution Vulnerability in `_.unset` and `_.omit` functions
Lodash versions 4.0.0 through 4.17.22 are vulnerable to prototype pollution in the `_.unset` and `_.omit` functions. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes.

The issue permits deletion of properties but does not allow overwriting their original behavior.

Prototype Pollution in lodash
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.

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.
