merge-deep node module before 3.0.1 suffers from a Modification of Assumed-Immutable Data (MAID) vulnerability, which allows a malicious user to modify the prototype of Object via proto, causing the addition or modification of an existing property that will exist on all objects.
The product does not properly protect an assumed-immutable element from being modified by an attacker.
