FKIE_CVE-2026-2918

Vulnerability from fkie_nvd - Published: 2026-03-11 08:16 - Updated: 2026-04-22 21:27
Severity ?
6.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
Summary
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 trav\u00e9s de la acci\u00f3n AJAX \u0027ha_condition_update\u0027. Esto se debe a que el m\u00e9todo \u0027validate_reqeust()\u0027 usa \u0027current_user_can(\u0027edit_posts\u0027, $template_id)\u0027 en lugar de \u0027current_user_can(\u0027edit_post\u0027, $template_id)\u0027 \u2014 lo que impide realizar una autorizaci\u00f3n a nivel de objeto. Adem\u00e1s, la acci\u00f3n AJAX \u0027ha_get_current_condition\u0027 carece de una verificaci\u00f3n de capacidad. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, modifiquen las condiciones de visualizaci\u00f3n de cualquier plantilla \u0027ha_library\u0027 publicada. Debido a que el renderizador \u0027cond_to_html()\u0027 genera valores de condici\u00f3n en atributos HTML sin un escape adecuado (usando concatenaci\u00f3n de cadenas en lugar de \u0027esc_attr()\u0027), un atacante puede inyectar atributos de gestor de eventos (por ejemplo, \u0027onmouseover\u0027) que ejecutan JavaScript cuando un administrador ve el panel de Condiciones de Plantilla, lo que resulta en Cross-Site Scripting Almacenado."
