I hit a problem with this:
System Nextcloud 18 - docker-fpm
Hitting the share symbol just leads to an Error reading file data.
I didn’t investigate further as the simple workaround is to rename the file.
But I think it a little spooky, as if filenames are not treated with enough separation from the code. I don’t hope a lovingly crafted filename could be used to execute code.
btw. Thanks for Nextcloud
