| Description | A stored cross-site scripting (XSS) vulnerability in Bludit 4.0.0-beta allows a low-privileged authenticated user (Author role) to inject arbitrary JavaScript by uploading a crafted SVG file as the site logo. The /admin/ajax/logo-upload endpoint in bl-kernel/ajax/logo-upload.php moves the uploaded file directly to the web root via Filesystem::mv() without invoking sanitizeSVG() or transformImage(), while SVG is present in the ALLOWED_IMG_EXTENSION and ALLOWED_IMG_MIMETYPES allow-lists. A stored script tag in the SVG executes in the browser of any user who loads the logo. | A stored cross-site scripting (XSS) vulnerability in Bludit 4.0.0-beta allows a low-privileged authenticated user (Author role) to inject arbitrary JavaScript by uploading a crafted SVG file as the site logo.
