CVE-2026-11616
Events Calendar for GeoDirectory <= 2.3.28 - Authenticated (Subscriber+) Privilege Escalation
Description
The Events Calendar for GeoDirectory plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 2.3.28. This is due to the ajax_ayi_action() handler only applying strip_tags(esc_sql()) — with no allow-list — to the attacker-controlled $_POST['type'] and $_POST['postid'] values before forwarding them to update_ayi_data(), which calls update_user_meta($current_user->ID, $rsvp_args['type'], $posts). By passing type=wp_capabilities and postid=administrator, an attacker writes ['subscriber'=>true,'administrator'=>'administrator'] into their own wp_capabilities user meta; WP_User::get_role_caps() then treats the 'administrator' array key as an active role on the next request. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to Administrator.

Action Type Old Value New Value Added Translation Title: plugin de WordPress Events Calendar for GeoDirectory, Description: El plugin The Events Calendar for GeoDirectory para WordPress es vulnerable a escalada de privilegios en versiones hasta la 2.3.28 inclusive. Esto se debe a que el gestor ajax_ayi_action() solo aplica strip_tags(esc_sql()) - sin lista de permitidos - a los valores $_POST['type'] y $_POST['postid'] controlados por el atacante antes de reenviarlos a update_ayi_data(), que llama a update_user_meta($current_user->ID, $rsvp_args['type'], $posts). Al pasar type=wp_capabilities y postid=administrator, un atacante escribe ['subscriber'=>true,'administrator'=>'administrator'] en sus propios metadatos de usuario wp_capabilities; WP_User::get_role_caps() luego trata la clave de array 'administrator' como un rol activo en la siguiente solicitud. Esto hace posible que los atacantes autenticados, con acceso de nivel Suscriptor o superior, eleven sus privilegios a Administrador. -
