Crumbs – Moderately Critical – Cross Site Scripting (XSS) – SA-CONTRIB-2015-082

Description

This module enables you to add navigation to your webpages colloquially referred to as “breadcrumbs”.

The module doesn’t sufficiently sanitize custom HTML separators for breadcrumbs, thereby exposing a Cross Site Scripting vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission “Administer Crumbs”.
