Description

This affects all versions of package mout. The deepFillIn function can be used to &#39;fill missing properties recursively&#39;, while the deepMixIn &#39;mixes objects into the target object, recursively mixing existing child objects as well&#39;. In both cases, the key used to access the target object recursively is not checked, leading to a Prototype Pollution.
