This affects all versions of package nedb. The library could be tricked into adding or modifying properties of Object.prototype using a proto or constructor.prototype payload.

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.
