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.
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.
