  script_tag(name:"insight", value:"Multiple flaws are due to:

  - An error in the legacy theme preview implementation within the  file
   'wp-includes/theme.php', which is not properly handling the user input.

  - An error in the function 'refreshAdvancedAccessibilityOfItem' within file
    'wp-admin/js/nav-menu.js', which is not properly handling the user input.

  - An error in the function 'WP_Nav_Menu_Widget' class within file
   'wp-includes/default-widgets.php', which is not properly handling the user
    input.

  - The function 'wp_untrash_post_comments' is not properly handling a comment
    after retrieving from trash within the file 'wp-includes/post.php'

  - The no usage of constant time comaprision for widgets in function
    'sanitize_widget_instance' leads to timing side-channel attack by measuring
    the delay before inequality is calculated which is
    within the file 'wp-includes/class-wp-customize-widgets.php'

  - The Cross-site request forgery (CSRF) vulnerability in 'wp-admin/post.php'");

  script_tag(name:"impact", value:"Successfully exploiting will allow
  remote attackers to inject arbitrary web script code in a user's browser
  session within the trust relationship between their browser and the server,
  to inject or manipulate SQL queries in the back-end database and to cause
  denial of service.");
