Hi Andre,
I think this is a security issue, the file execution is out of control. This security issue has been recognized and fixed by many organizations.

Not really a Kleopatra issue but GpgEX (just for the record as kde@xxxxxxx is
in CC).

Ok, its a bug but I don't think this is really a security isse as an execution
prevention that blocks unknown binaries from beeing executed is not bypassed
and on default windows the creation of a file in c:\ requires administrative
privileges. But I see that it can be an issue with non default installation
paths.
I can reproduce it with the latest version and I have seen similar issues with
create process in the past. The issue for this is now https://dev.gnupg.org/
T5272 and I'll fix it before the next release.
Best Regards,
Andre
