These days many people do not consider post-authentication vulnerabilities dangerous, such as Stored XSS in the administrator’s portion of a web application.

This situation is probably aggravated by some misinformation websites and some self-proclaimed security experts, which try to deny disclosed vulnerabilities by posing them as a feature implemented by design. The problem is that they simply do not understand the exploitation’s vectors of these vulnerabilities and they consider them as benign, as long as they impact webpages which do not remain available to unauthenticated users.
