Which of the following involves sending arbitrary characters in a web page request?

XSS stands for cross-site scripting, which is a web security vulnerability that allows an attacker to inject malicious code into a web page that is viewed by other users1. XSS involves sending arbitrary characters in a web page request, such as a query string, a form field, a cookie, or a header, that contain a malicious script. The web server does not validate or encode the input, and returns it as part of the web page response. The browser then executes the script, which can perform various actions on behalf of the attacker, such as stealing cookies, session tokens, or other sensitive information, redirecting the user to a malicious site, or displaying fake content
