ISSUE:
The <base> tag is parsed outside of <head></head>. This can lead to
the base being reset, both before and after the <base> tag being
injected, depending on browser types and versions. As a result, images
and javascript can be loaded from an attackers domain, and forms and
hyperlinks point to the attackers domain.

Erm... so you're basically assumint that the attacker can inject stuff
into the page? If that's the case, you should have other issues than
your links getting altered or so, no? E.g. what about javascript
injection?
