XSS, or Cross-Site Scripting, is a vulnerability that allows attackers to inject malicious scripts into web pages viewed by users. To prevent XSS, you can validate and sanitize user inputs, use Content Security Policy (CSP), and escape outputs.

Can you give me an example of an XSS attack?

Sure! An example of an XSS attack is when an attacker injects a script into a comment section of a blog. When other users view the comment, the script runs in their browsers, potentially stealing cookies or session tokens.

What tools can I use to test for XSS vulnerabilities?

You can use tools like OWASP ZAP, Burp Suite, or even browser extensions like XSS Me to test for XSS vulnerabilities in your web applications.

Are there different types of XSS attacks?
