Prototype pollution vulnerability in dot-prop npm package versions before 4.2.1 and versions 5.x before 5.1.1 allows an attacker to add arbitrary properties to JavaScript language constructs such as objects.
The product does not properly protect an assumed-immutable element from being modified by an attacker.
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.
