Description Pedro Sampaio 2018-02-15 13:50:28 EST 
Affected versions of this package are vulnerable to Prototype Pollution. The utilities function allows modification of the Object prototype. If an attacker can control part of the structure passed to this function, they could add or modify an existing property leading to potential denial of service.

Upstream patch:

Comment 3 Jason Shepherd 2018-02-16 00:18:25 EST 
Node of the libraries, or services using the lodash in RHMAP call the vulnerable methods with the expection of the _send function in 'sendgrid' version 1.9.1. For 'sendgrid' the parameters passed to 'lodash.merge' are not obtained from user input:
