exploited by malicious people to conduct cross-site scripting attacks
and disclose sensitive information.

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

sanitised before being used to view files. This can be exploited to
disclose the contents of arbitrary files via directory traversal
attacks.
