Thread:User talk:Dantman/BreadCrumbs2 - What's wrong with it?

Ack! An extension I'm using has been marked as a "Code Injection" risk.

http://www.mediawiki.org/wiki/Extension:BreadCrumbs2

Why was it marked and how do I fix it?

Also, is it an issue of the wiki or the MediaWiki:Breadcrumbs page are read-only to all but Administrators?
