hoolock is a suite of lightweight utilities designed to maintain a small footprint when bundled. Starting in version 2.0.0 and prior to version 2.2.1, utility functions related to object paths (get, set, and update) did not block attempts to access or alter object prototypes. Starting in version 2.2.1, the get, set and update functions throw a TypeError when a user attempts to access or alter inherited properties.

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.
