    Summary: assign-deep Vulnerable to Prototype Pollution

    Details: Versions of `assign-deep` prior to 1.0.1 and 0.4.8 are vulnerable to Prototype Pollution. The `assign` 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 Upgrade to versions 1.0.1, 0.4.8, or later.
