Code exposure vulnerability in HTML5 applications

6/10 Medium

HTML5 files (HTML, CSS, JavaScript) are cached and rendered on the user's system, making them easily accessible and viewable by anyone. HTML5 encryption cannot work because browsers cannot execute encrypted content, forcing developers to use code minification and obfuscation as incomplete solutions.
