doesn't support file uploads from browsers (yet), so they can't exploit

+It is possible to embed an image in a page edited over the web, by using
+`img src="data:image/png;"`. Ikiwiki's htmlscrubber only allows `data:`
+urls to be used for `image/*` mime types. It's possible that some broken
+browser might ignore the mime type and if the data provided is not an
+image, instead run it as javascript, or something evil like that. Hopefully
+not many browsers are that broken.

+The htmlscrubber did not block javascript in uris. This was fixed by adding

+This hole was discovered on 10 February 2008 and fixed the same day
+with the release of ikiwiki 2.31.1. A fix was also backported to Debian etch,
+as version 1.33.4. I recommend upgrading to one of these versions if your
+wiki can be edited by third parties.
