What is an XSS vector?
Cross site scripting (XSS) is a common attack vector that injects malicious code into a vulnerable web application. It occurs when a malicious script is injected directly into a vulnerable web application. Reflected XSS involves the reflecting of a malicious script off of a web application, onto a user’s browser.
What is major difference between XSS and CSRF?
The key difference between those two attacks is that a CSRF attack requires an authenticated session, while XSS attacks don’t. Some other differences are: Since it doesn’t require any user interaction, XSS is believed to be more dangerous. CSRF is restricted to the actions victims can perform.
When to use XSS when reading an email?
Nowadays XSS via email is only really relevant when reading an email with a web browser. Modern mail clients no longer parse scripts by default. The mail service in which you’re reading the email (as the target/victim) would need to have an available XSS injection point for an attacker to take advantage.

Do you need XSS injection point for email?

Can a web browser parse an email script?
