I see. You can use an older version, but over time there will most likely be security issues, which become known. So this version is then insecure.

The only thing that was changed by the fix for this bug is what the installer and the updater check when you install or update MediaWiki. Updating means using the maintenance script update.php. You do not need this script for minor updates. That means you will in fact be able to update to 1.22.2 and 1.22.3 and so on as long as you do not run update.php (which you do not have to do for minor updates anyway). But you will not be able to go to 1.23 or 1.24 once they are out.
