CVE-2025-47778Network attack vector

Server-side data access via external SVG entities

Published May 14, 2025 · Updated May 14, 2025

XXE in the Sulu SVG file inspector allows remote authenticated users to load external data through a crafted media upload. SvgFileInspector passes uploaded SVG text to DOMDocument::loadXML with LIBXML_NOENT and LIBXML_DTDLOAD, enabling entity substitution and external DTD loading. Administrative media-upload privileges are required, and successful exploitation makes the server retrieve attacker-selected external resources during XML processing.
