There is no line about cdrom in /etc/fstab. Cdrom are usually mounted
under /media/<user>/cdrom or something like that. Since audio CD are not
mounted, any user can eject them. This could be a good point for your
suspicion (or is it "suspect"? Sorry, english is not my language).

Anyway, here is the output from mount about a CDROM:

/dev/sr0 on /media/andrea/CDROM type iso9660
(ro,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500,uhelper=udisks2)

Hope this is useful, thanks.
