"According to its self-reported version number, the WordPress application running on the remote web server is affected
by multiple vulnerabilities:
  - An open redirect vulnerability exists in WordPress due to improper sanitization of user-supplied input to HTTP 
  request parameters. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially 
  crafted link, to redirect a user to a malicious website. (CVE-2019-16220)

  - Multiple cross-site scripting (XSS) vulnerabilities exist in WordPress due to improper validation of user-supplied 
  input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to 
  click a specially crafted URL, to execute arbitrary script code in a user's browser session. 
  (CVE-2019-16217, CVE-2019-16218, CVE-2019-16219, CVE-2019-16221, CVE-2019-16222, CVE-2019-16223)
