CVE-2026-8991Network attack vector

Administrator-level stored XSS via unescaped uploader settings

Published Jun 6, 2026 · Updated Jun 6, 2026

Stored XSS in CodeDropz Drag and Drop Multiple File Upload for Contact Form 7 1.3.9.7 and earlier allows remote authenticated users to run scripts. The plugin stores the drag_n_drop_text and drag_n_drop_browse_text settings without sufficient sanitization and renders them into page markup and JavaScript without context-appropriate escaping. Administrator-level access is required to plant the payload; it then executes for visitors who load a page containing the affected upload form.
