Lodash has Prototype Pollution Vulnerability in `_.unset` and `_.omit` functions

### Impact 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. ### Patches This issue is patched on 4.17.23.
