Cross-site scripting (XSS) is an attack that allows JavaScript from one site to run on another. XSS is interesting not due to the technical difficulty of the attack but rather because it exploits some of the core security mechanisms of web browsers and because of its sheer pervasiveness. Understanding XSS and its mitigations provides substantial insight into how the web works and how sites are safely (and unsafely) isolated from each other.
