This is due to missing nonce verification on the plugin's settings update forms handled in bottom-bar-admin.php. None of the three settings forms (main settings, sharing services, restore defaults) include a wp_nonce_field(), and the server-side processing code never calls check_admin_referer() or any equivalent nonce validation before processing POST data and calling update_option(). This makes it possible for unauthenticated attackers to trick a logged-in administrator into submitting a crafted request that updates plugin configuration options, such as changing the language, maximum post counts, or enabled sharing services."}, {"lang": "es", "value": "El plugin Bottom Bar para WordPress es vulnerable a la falsificaci\u00f3n de petici\u00f3n en sitios cruzados en todas las versiones hasta la 0.1.7 inclusive.

Ninguno de los tres formularios de configuraci\u00f3n (configuraci\u00f3n principal, servicios para compartir, restaurar valores predeterminados) incluye un wp_nonce_field(), y el c\u00f3digo de procesamiento del lado del servidor nunca llama a check_admin_referer() ni a ninguna validaci\u00f3n de nonce equivalente antes de procesar los datos POST y llamar a update_option().
