Stored XSS via unsanitized SVG uploads
Published Apr 11, 2025 · Updated Apr 8, 2026
Stored XSS in WPZita Z Companion 1.1.1 and earlier allows remote authenticated users to run scripts through uploaded SVG files. The upload path accepts active SVG/XML content without the wp_handle_upload_prefilter sanitization hook or output escaping, so embedded script remains executable. Author-level access and the Royal Shop theme are required, and execution occurs only when another user accesses the uploaded SVG file.
