All versions of package jsgui-lang-essentials are vulnerable to Prototype Pollution due to allowing all Object attributes to be altered, including their magical attributes such as proto, constructor and prototype.
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.
