Java: Cross-Site Scripting (XSS)
Answer
HTML encoding converts special characters to HTML entities.
HTML encoding is crucial in Java web applications to prevent Stored XSS attacks. When user input is stored in a database and later displayed on a web page, encoding translates characters like '' into '<' and '>', neutralizing malicious scripts. For example, in a Java servlet, using `org.apache.commons.text.StringEscapeUtils.escapeHtml4()` can safely encode user inputs before storing or displaying them.
