Cross-Site Scripting (XSS) attacks allow attackers to inject malicious scripts into a website, executing them on the victim's browser. In React, XSS typically occurs when user input is not properly sanitized or escaped. To prevent XSS in React, use `jsx` and `html` escape functions, libraries like Helmet, validate and sanitize user input, and implement a Content Security Policy (CSP).
Implementing robust security measures is crucial for full-stack developers to stay ahead of potential attackers. This involves configuring systems or applications to minimize their attack surface through security hardening, and proactively identifying and addressing potential security weaknesses through vulnerability prevention.
