If the user is an admin then there can be a capacity for the assailant taking the admin qualifications and taking over the site.

The non-profit Open Web Application Security Project (OWASP) describes this sort of vulnerability:

“Shown attacks are those where the injected script is shown off the web server, such as in an error message, search result, or any other action that includes some or all of the input sent to the server as part of the demand.
