Explanation

XSS vulnerabilities occur when web applications output unvalidated user input to HTML without proper encoding. This can happen in any language (Java, ASP.Net, Perl, PHP, Python, etc.) - it's a web application vulnerability, not language-specific.

AI explanation

Cross-site scripting is a vulnerability in how untrusted data is rendered into a page's output, not a flaw tied to any one server-side language. Any language used to generate dynamic HTML — Java, ASP.NET, Perl, or others — can produce an XSS hole if output isn't properly encoded, so all of them are susceptible.
