can be exploited by malicious people to conduct cross-site scripting
attacks and potentially compromise a vulnerable system.

returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of a vulnerable
site.

used to include files. This can be exploited to include arbitrary
files from external and local resources.
