Technical details
An XML External Entity (XXE) injection vulnerability exists in ContentWorker's rendering functions (renderContentAsText and related CMS/help render paths). An attacker with content-author permission can craft a malicious text/xml DataResource containing external entity declarations; when FreeMarker renders this content, its default DocumentBuilderFactory parses the XML without FEATURE_SECURE_PROCESSING or external-entity/DTD restrictions, allowing entity resolution and arbitrary file disclosure or server-side request forgery (SSRF).
