The software in question would be „Canon IJ Network Scanner Selector EX2 2.0.15.2“ and „Canon IJ Scan Utility 1.7.0.5“ I do see them on „UCheck“ and „UpdateStar“ (R.I.P „Sumo“), though the updates are either not available to download or under a paywall. Having software for a 2022 product having a copyright date of 2010-2018 is a bit stupid. I did find the updated „IJ Printer Assistant Tool“ since it's hosted separately from the driver package on some random model. The main concern of course is security... anything to do with networking is bound to have bug/security fixes.
