- Advisory ID: DRUPAL-SA-CONTRIB-2010-032

- Versions: 6.x-1.x, 5.x-1.x
- Date: 2010-March-31
- Security risk: Critical
- Exploitable from: Remote
- Vulnerability: Cross Site Scripting
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) vulnerability. XSS vulnerabilities may lead to compromise of administrative accounts or other attacks against site visitors.
