- 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.");
