  - CVE-2021-40848: Exported CSV files could contain characters that a spreadsheet program could
  interpret as a command, leading to execution of a malicious string locally on a device, aka CSV
  injection.

  - CVE-2021-40849: The account associated with a web services token is vulnerable to being
  exploited and logged into, resulting in information disclosure (at a minimum) and often
  escalation of privileges.

  - CVE-2021-43264: Adjusting the path component for the page help file allows attackers to bypass
  the intended access control for HTML files via directory traversal. It replaces the - character
  with the / character.

  - CVE-2021-43265: Certain tag syntax could be used for XSS, such as via a SCRIPT element.

  - CVE-2021-43266: Exporting collections via PDF export could lead to code execution via shell
  metacharacters in a collection name.");
