Malicious Injection Prompt - Copy this React, Mui Component to your project

Generate an AI prompt to explain how a malicious actor could exploit a website by injecting malicious code into a vulnerable input field, leading to a cross-site scripting (XSS) attack. The prompt should highlight the consequences of injecting code like <img src=q onerror=alert(document.cookie)>, which could lead to the execution of JavaScript code that steals sensitive information, such as cookies, from unsuspecting users. Additionally, emphasize the importance of proper input validation and sanitization to prevent such attacks.
