Duplicate Advisory: web3-utils Prototype Pollution vulnerability

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-2g4c-8fpm-c46v. This link is maintained to preserve external references.

Original Description

Versions of the package web3-utils before 4.2.1 are vulnerable to Prototype Pollution via the utility functions format and mergeDeep, due to insecure recursive merge.
An attacker can manipulate an object's prototype, potentially leading to the alteration of the behavior of all objects inheriting from the affected prototype by passing specially crafted input to these functions.
