Background
The package graphql-shield is an authorization library for GraphQL servers. It provides a way to define and enforce permissions for GraphQL operations. By specifying rules, developers can control access to certain data or actions within their GraphQL API. However, versions prior to 6.0.6 of graphql-shield are vulnerable to an Authorization Bypass.
Vulnerability Detail
The vulnerability in graphql-shield arises from the use of cryptographically insecure functions to generate keys for rule caching.

This can lead to unauthorized access to sensitive data or actions within the GraphQL API.
