  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.

  metacharacters in a collection name.");
