Prototype Pollution on lodash

[CH-Chonsu]

Hi there

We're gladly using grunt-update-json on many of our products.

You're using lodash version ~2.x. It contains the vulnerability "prototype pollution", which is fixed in lodash version >= 4.17.12.

Therefore we recommend and kindly ask you to update your dependencies!

Thanks a lot in advance and stay healthy!

Greetings Corina
