The commit dcd3b86 explicitly shows the removal of '.svg' from the FileExtensionWhiteList() in FileUpload.fnc.php, with the comment stating this fixes a stored XSS issue. SVG files are inherently risky for XSS as they can contain executable scripts, and allowing them without sanitization creates a direct vulnerability. The patch confirms this was the attack vector by disabling SVG uploads.
