In some circumstances, it was possible to export data in CSV format that could trigger a payload in old versions of Excel.
If you are accepting user input from untrusted sources and will be exporting that data in CSV format from element index pages and there is a chance users will open that on old versions of Excel, then you should update.
This has been patched in Craft 3.7.14.
