Stored XSS description from OWASP
occurs when a web application gathers input from a user which might be malicious, and then stores that input in a data store for later use. The input that is stored is not correctly filtered. As a consequence, the malicious data will appear to be part of the web site and run within the user’s browser under the privileges of the web application. Since this vulnerability typically involves at least two requests to the application, this may also called second-order XSS.
