Overview

Versions of set-value prior to 3.0.1 or 2.0.1 are vulnerable to Prototype Pollution. The set 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 set-value 3.x, upgrade to version 3.0.1 or later.
If you are using set-value 2.x, upgrade to version 2.0.1 or later.
