Advisories for Npm/Mixin-Deep package

mixin-deep is vulnerable to Prototype Pollution. The function mixin-deep could be tricked into adding or modifying properties of Object.prototype using a constructor payload.

mixin-deep node 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.

Utilities function in mixin-deep can be tricked into modify the prototype of "Object" when the attacker control part of the structure passed to these function. This can let an attacker add or modify existing property that will exist on all object, leading to denial of service or remote code execution.
