HTML5 introduced powerful features that enhanced the functionality and user experience of web applications. However, these capabilities also expanded the attack surface, making web applications vulnerable if security controls are not properly implemented. Attackers exploit HTML5 APIs and browser features to compromise confidentiality, integrity, and availability of web applications. Therefore, understanding HTML5-based attacks and implementing appropriate security measures are essential aspects of web application testing and security auditing. One common HTML5 attack involves Cross-Site Scripting (XSS). HTML5 supports dynamic content and client-side scripting, allowing attackers to inject malicious JavaScript into web pages.
