Vulnerabilidad · Publicado 16/08/2026
El plugin Solace Extra en versiones hasta 1.6.0 permite a atacantes no autenticados modificar o eliminar datos a través de la función import_zip() que carece de validación de permisos. La vulnerabilidad afecta sitios WordPress en México y LATAM que usan este plugin, exponiendo contenido, configuraciones y bases de datos. La verificación de nonce insuficiente permite bypass de controles de seguridad estándar de WordPress.
The Solace Extra plugin for WordPress is vulnerable to unauthorized modification and loss of data due to a missing capability check on the import_zip() function in versions up to, and including, 1.6.0. The handler is registered on both wp_ajax_action-import-zip and wp_ajax_nopriv_action-import-zip and only verifies the 'ajax-nonce' nonce, which is emitted on every admin page via wp_localize_script (unrestricted admin_enqueue_scripts hook) and is therefore accessible to any authenticated user including Subscribers. This makes it possible for authenticated attackers, with Subscriber-level access and above, to wipe navigation menus, sidebar widgets (via update_option('sidebars_widgets', array())), all theme mods (via remove_theme_mods()), and Elementor templates, as well as trigger arbitrary demo-content imports.
