I have already worked with the Client and Vendor and the vendor is providing a free upgrade to the customer for no 
charge to correct the vulnerable issue. 
My focus is to protect the customer first...   The customer agreed that the vulnerability could be disclosed after they 

So I guess the only part of this I didn't care for was the vendor saying that they did not want me to release this
