Open Source Vulnerabilities GHSA-4g88-fppr-53pp

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.
