Would it be possible to apply the updates from the latest security update for Coppermine 1.4.27 to the Modpack 1.4.26?

Go ahead and do that. You'll need a diff viewer and some extra time, that's all. Once you have done that, package your changes and let others benefit from your work.
Stramm has released his modpack for cpg1.4.27 - see http://forum.coppermine-gallery.net/index.php/topic,65217.0.html. Closing, locking.
