What is stored cross site scripting or stored XSS?
What is stored cross-site scripting? Stored cross-site scripting (also known as second-order or persistent XSS) arises when an application receives data from an untrusted source and includes that data within its later HTTP responses in an unsafe way.
How does a cross site scripting attack work?
