• CVE-2017-5493

• CVE-2017-5610

  wp-admin/includes/class-wp-press-this.php in Press This in WordPress before 4.7.2 does not properly restrict visibility of a taxonomy-assignment user interface, which allows remote attackers to bypass intended access restrictions by reading terms.

• CVE-2017-5611

  SQL injection vulnerability in wp-includes/class-wp-query.php in WP_Query in WordPress before 4.7.2 allows remote attackers to execute arbitrary SQL commands by leveraging the presence of an affected plugin or theme that mishandles a crafted post type name.

• CVE-2017-5612

  Cross-site scripting (XSS) vulnerability in wp-admin/includes/class-wp-posts-list-table.php in the posts list table in WordPress before 4.7.2 allows remote attackers to inject arbitrary web script or HTML via a crafted excerpt.
