CVE-2021-4396
Estado: ModificadaMedia (4.3)—
El plugin Rucy para WordPress es vulnerable a falsificación de petición en sitios cruzados (CSRF) en las versiones hasta la 0.4.4 inclusive. Esto se debe a una validación de nonce ausente o incorrecta en la función save_rc_post_meta(). Esto hace posible que atacantes no autenticados guarden metadatos de entradas mediante una petición falsificada, siempre que consigan engañar a un administrador del sitio para que realice una acción, como hacer clic en un enlace.
