Authenticated stored XSS via unsanitized SVG uploads
Published Oct 1, 2024 · Updated Apr 8, 2026
Stored XSS in QuomodoSoft QS Dark Mode Plugin 2.9 and earlier allows remote authenticated users to inject scripts through SVG uploads. The plugin accepts SVG files without sufficient input sanitization or output escaping, allowing embedded JavaScript to persist in uploaded media. Author-level access or higher is required, and the script runs in a visitor's browser when the uploaded SVG file is accessed.
