Prototype Pollution in mixin-deep

Versions of mixin-deep prior to 2.0.1 or 1.3.2 are vulnerable to Prototype Pollution. The mixinDeep function fails to validate which Object properties it updates. This allows attackers to modify the prototype of Object, causing the addition or modification of an existing property on all objects.

Recommendation

If you are using mixin-deep 2.x, upgrade to version 2.0.1 or later.
If you are using mixin-deep 1.x, upgrade to version 1.3.2 or later.
