CVE-2025-13989Network attack vectorHinoki check available

Stored XSS via executable callback shortcode attribute

Published Dec 12, 2025 · Updated Dec 12, 2025

Stored XSS in Nazmul Sabuz WP Dropzone 1.1.1 and earlier allows remote authenticated users to inject scripts through callback. The shortcode handler places the user-controlled callback attribute into inline configuration, and client-side code compiles it with new Function() without sanitization or escaping. Contributor-level access is sufficient; the script runs when a user opens the affected post or page, permitting actions in that user's browser context.
