CVE-2025-47778: Sulu vulnerable to XXE in SVG File upload Inspector
Description
Sulu is an open-source PHP content management system based on the Symfony framework. Starting in versions 2.5.21, 2.6.5, and 3.0.0-alpha1, an admin user can upload SVG which may load external data via XML DOM library. This can be used for insecure XML External Entity References. The problem has been patched in versions 2.6.9, 2.5.25, and 3.0.0-alpha3. As a workaround, one may patch the effect file `src/Sulu/Bundle/MediaBundle/FileInspector/SvgFileInspector.php` manually.
