The user probably doesn't have permission to write to the /dev/cdrom1
device. I usually make my cdrom and burner world-writable, which isn't
a good idea on a multi-user system.
The user is able to mount the device because mount runs as root. After
that, the only permissions that are checked are on the mount point.

Yep, same problem. You'll also see it if you try to play an audio cd.
