Prototype poisoning in function mapObjIndexed in Ramda 0.27.0 and earlier allows attackers to compromise integrity or availability of application via supplying a crafted object (that contains an own property proto) as an argument to the function. NOTE: the vendor disputes this because the observed behavior only means that a user can create objects that the user didnt know would contain custom prototypes

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.
