CVE-2026-2918
The Happy Addons for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.21.0 via the `ha_condition_update` AJAX action. This is due to the `validate_reqeust()` method using `current_user_can('edit_posts', $template_id)` instead of `current_user_can('edit_post', $template_id)` — failing to perform object-level authorization. Additionally, the `ha_get_current_condition` AJAX action lacks a capability check.

This makes it possible for authenticated attackers, with Contributor-level access and above, to modify the display conditions of any published `ha_library` template. Because the `cond_to_html()` renderer outputs condition values into HTML attributes without proper escaping (using string concatenation instead of `esc_attr()`), an attacker can inject event handler attributes (e.g., `onmouseover`) that execute JavaScript when an administrator views the Template Conditions panel, resulting in Stored Cross-Site Scripting.

"value": "El plugin Happy Addons para Elementor para WordPress es vulnerable a Referencia Directa a Objeto Insegura en todas las versiones hasta la 3.21.0, inclusive, a través de la acción AJAX 'ha_condition_update'. Esto se debe a que el método 'validate_reqeust()' usa 'current_user_can('edit_posts', $template_id)' en lugar de 'current_user_can('edit_post', $template_id)' — lo que impide realizar una autorización a nivel de objeto. Además, la acción AJAX 'ha_get_current_condition' carece de una verificación de capacidad. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, modifiquen las condiciones de visualización de cualquier plantilla 'ha_library' publicada. Debido a que el renderizador 'cond_to_html()' genera valores de condición en atributos HTML sin un escape adecuado (usando concatenación de cadenas en lugar de 'esc_attr()'), un atacante puede inyectar atributos de gestor de eventos (por ejemplo, 'onmouseover') que ejecutan JavaScript cuando un administrador ve el panel de Condiciones de Plantilla, lo que resulta en Cross-Site Scripting Almacenado."
