# Tutorial 27:  OpenZeppelin Vulnerabilities

{% hint style="info" %}
[**Book an audit with Zokyo**](https://www.zokyo.io/)
{% endhint %}

### Introduction

This tutorial is aimed at blockchain auditors and developers to enhance awareness regarding vulnerabilities in different versions of OpenZeppelin contracts. OpenZeppelin libraries are widely used in the development of Ethereum smart contracts due to their robust, community-audited code. However, vulnerabilities can still be found in various versions, affecting multiple projects across the blockchain ecosystem.

The focus of this tutorial is to guide users on how to:

* **Identify Vulnerable Versions**: Instructions will be provided on how to recognize versions of OpenZeppelin contracts that are known to be vulnerable.
* **Inspect Imports and Dependencies**: Guidance on how to scrutinize the OpenZeppelin contracts, libraries, and NPM packages that are imported into your projects to ensure they are secure and updated.
* **Utilize Resources for Vulnerability Information**: Introduction to resources that offer updated information on identified vulnerabilities in OpenZeppelin contracts, aiding in making informed decisions during development and auditing processes.

The objective is to foster a practice of continuous vigilance and updating necessary to maintain the security integrity of smart contracts that leverage OpenZeppelin libraries and contracts.
