Blu-Ray Finalize Vulnerability?

I work for a large Defense Contractor and we require closed and closely monitored media. Much of the data we use comes to us on Blu-Ray discs that are scanned/finalized and approved to be in a classified space. We just received word from our Program Security that there is some sort of vulnerability where Blu-Ray discs cannot be closed/finalized, so we are to put a hard-stop on using them. Does anyone have information on this? I haven't been able to find anything...yet.

The fact they CAN'T be finalized is what makes them rewritable! I found a great article here on dealing with "unfinalized vs closing" disks.
