CVE, Research URL: CVE-2025-13452
Home page URL: Security reports for Admin and Customer Messages After Order for WooCommerce: OrderConvo
Application: Admin and Customer Messages After Order for WooCommerce: OrderConvo
Published on: Nov 25, 2025
Research Description: The Admin and Customer Messages After Order for WooCommerce: OrderConvo plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 14. This is due to a flawed permission check in the REST API permission callback that returns true when no nonce is provided. This makes it possible for unauthenticated attackers to impersonate any WordPress user and inject arbitrary messages into any WooCommerce order conversation by directly calling the REST endpoint with controlled user_id, order_id, and context parameters.
Affected versions: max 14.
Status: vulnerable
