Then ask your admin what has changed.

This confuses me, which OS is actually hosting Bugzilla? The mentioned
path and permissions don't sound like Windows and the error in general
is mostly not related to any browser-based client.

If you are hosting under Windows, I suggest testing uploads with
ProcMon running to really see what happens when trying to access the
temporary directory.

So "GCItemp51995" is more likely "CGItemp51995", isn't it? Anyway, I
can't find any reference to such a directory in my CGI 4.35 of Perl
5.22, but ONLY for some older versions of that lib. In those, a
package named CGITempFile created directories like yours, but that
package has been removed in newer versions.

https://metacpan.org/source/LEEJO/CGI-4.38/lib/CGI.pod#L1058

https://www.perl-community.de/bat/poard/thread/176
https://foswiki.org/Tasks/Item13172

So I suggest searching your whole system hosting Bugzilla for CGI.pm
files and check their versions, which of those relate to the Perl you
think your are using for Bugzilla etc.

That's how you expect things to work, but the error message reads
otherwise to me. That sounds like the random directory is NOT created
(anymore?) for some reason.

So you need to check if such a directory should really be created
automatically at all, which heavily depends on the version of CGI.pm
in use. Afterwards you need to check if something is silently
preventing creation of that directory for some reason.

I'm thinking of something like private temp files of systemd, or some
container or chroot-stuff or alike which has recently changed for you.
It might even be that some older CGI.pm is used now which is not
supposed to work in your environment at all anymore something like
that.

In any case, I'm somewhat sure now that something important has
changed in your setup and you need to find what that was.

Mit freundlichen Grüßen,

Thorsten Schöning
