Django XSS: Examples and Prevention

Python's versatility has contributed to its popularity, especially in web development, where Django, a free and open-source framework, is widely used. Security is a critical concern in web applications, with cross-site scripting (XSS) being a prevalent threat where attackers inject malicious scripts into web applications. Django offers built-in security features, such as HTML escaping, to mitigate XSS attacks by converting HTML characters into their code equivalents, preventing script execution. However, attackers can bypass these defenses using techniques like base64 encoding, unquoted payloads, template literals, JavaScript embedded attributes, and unsafe use of Django's "safe" filter. To enhance security, developers must sanitize user inputs, avoid misuse of the "safe" filter, and employ measures like the HttpOnly flag to protect cookies from client-side access. Regular testing and security updates are crucial to maintaining robust defenses against XSS and other vulnerabilities.
