The function queries posts with post_status=any and returns full WP_Post objects including post_content, but only checks the generic edit_posts capability instead of verifying whether the requesting user has permission to read each individual post."},{"lang":"es","value":"El plugin Smart Custom Fields para WordPress es vulnerable al acceso no autorizado de datos debido a una comprobación de capacidad faltante en la función relational_posts_search() en todas las versiones hasta la 5.0.6, inclusive.
