This affects the package multi-ini before 2.1.2. It is possible to pollute an objects prototype by specifying the constructor.proto object as part of an array. This is a bypass of CVE-2020-28448.

Weakness

The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
