  - CVE-2020-14055: An attacker can store JavaScript code on the server, which might lead to
  information leakage like FTP credentials and can also affect other applications  running within
  the same origin.

  - CVE-2020-14056: An attacker can read arbitrary local files accessible by the webserver by
  exploiting this vulnerability. It might lead to information leakage from or manipulation of
  internal services.

  - CVE-2020-14057: An attacker can read and write arbitrary local files accessible by the webserver
  by exploiting the vulnerability. This might gain remote code execution by uploading PHP scripts in
  the web root and calling it via the webserver.");
