This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 85% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
