Description
Silverstripe CMS is an open source content management system. Prior to 6.2.1, page breadcrumbs in the CMS are vulnerable to cross-site scripting when viewed using the page list view, because page titles are rendered into the breadcrumb trail without being escaped. This issue is fixed in 6.2.1.
