Descriptions

WordPress before 4.2.3 does not properly verify the edit_posts capability, which allows remote authenticated users to bypass intended access restrictions and create drafts by leveraging the Subscriber role, as demonstrated by a post-quickdraft-save action to wp-admin/post.php.

Vulnerabilidad en WordPress en versiones anteriores a 4.2.3, no verifica adecuadamente la capacidad de edit_posts, lo que permite a usuarios remotos autenticados eludir las restricciones destinadas al acceso y crear borradores mediante el aprovechamiento del rol Subscriber, según lo demostrado por una acción post-quickdraft-save a wp-admin/post.php.
