What causes reflected XSS?
Reflected XSS arises when an application takes some input from an HTTP request and embeds that input into the immediate response in an unsafe way. With stored XSS, the application instead stores the input and embeds it into a later response in an unsafe way.
How reflected XSS can be exploited?
To exploit a reflective XSS, an attacker must trick the user into sending data to the target site, which is often done by tricking the user into clicking a maliciously crafted link.

Is XSS still possible?
Current XSS Vulnerabilities One need not look too hard (or too long) at the CVE and other vulnerability databases to see that XSS remains an active and widely practiced attack technique on the 2020 threat landscape.
Is XSS a server-side or client-side vulnerability?
XSS Injection has become a vulnerability commonly found in many web applications that enable the adversaries to run client side scripting to do some action at the client-side. But there is a way to also run the script at the server-side by exploiting an application called html-pdf. CVE-2019-15138
