-------- DESCRIPTION  
---------------------------------------------------------
The Taxonomy Breadcrumb module generates taxonomy based breadcrumbs on node
pages and taxonomy/term pages. This module does not properly sanitize
taxonomy term name and, for 6.x, node titles when displayed in breadcrumbs,
leading to a Cross Site Scripting (XSS [1]) vulnerability. XSS
vulnerabilities may lead to compromise of administrative accounts or other
attacks against site visitors.

Breadcrumb module, there is nothing you need to do.
