That lines up with what we have encountered so far. All the sites having issues have been upgraded to PHP 8. So I guess we will disable that rule for now and wait for the update.
There is one more concern I had mentioned in my description above. The Live Traffic view is not showing these uploads being blocked (even if the All Traffic switch is turned on). It would be super helpful in diagnosing upload errors if the firewall log showed some sort of entry for when it blocks file uploads.
Is this how the Live Traffic feature is meant to work?
@wfphil I have submitted the diagnostics.
