All versions of package @ianwalter/merge are vulnerable to Prototype Pollution via the main (merge) function. Maintainer suggests using @generates/merger instead.

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.
