  script_tag(name:"insight", value:"The flaws exist because WordPress relies on the Host HTTP header for a password-reset e-mail message,
  which makes it easier for user-assisted remote attackers to reset arbitrary passwords by making a crafted wp-login.php?action=lostpassword
  request and then arranging for this e-mail to bounce or be resent, leading to transmission of the reset key to a mailbox on an
  attacker-controlled SMTP server. This is related to problematic use of the SERVER_NAME variable in wp-includes/pluggable.php in
  conjunction with the PHP mail function.");

  This may aid in further attacks.");

  product or replace the product by another one.

  A workaround is to enable UseCanonicalName to enforce static SERVER_NAME value.");
