Descriptions

Cross-site request forgery (CSRF) vulnerability in wp-admin/post.php in WordPress before 4.2.4 allows remote attackers to hijack the authentication of administrators for requests that lock a post, and consequently cause a denial of service (editing blockage), via a get-post-lock action.

Vulnerabilidad de CSRF en wp-admin/post.php en WordPress en versiones anteriores a 4.2.4 permite a atacantes remotos secuestrar la autenticación de los administradores para peticiones que bloquean una entrada, y por tanto causar una denegación de servicio (bloqueo de edición), a través de una acción get-post-lock.

Several vulnerabilities have been fixed in Wordpress, the popular blogging engine.
