Descriptions

The EventON - WordPress Virtual Event Calendar Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.5.4 (for Pro) & 2.2.7 (for Free). This is due to missing or incorrect nonce validation on the evo_eventpost_update_meta function. This makes it possible for unauthenticated attackers to update arbitrary post metadata via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

El complemento EventON - WordPress Virtual Event Calendar Plugin para WordPress es vulnerable a Cross-Site Request Forgery en todas las versiones hasta 4.5.4 (para Pro) y 2.2.7 (gratis), incluidas. Esto se debe a una validación nonce faltante o incorrecta en la función evo_eventpost_update_meta. Esto hace posible que atacantes no autenticados actualicen metadatos de publicaciones arbitrarias a través de una solicitud falsificada, siempre que puedan engañar al administrador del sitio para que realice una acción como hacer clic en un enlace.
