Netgear R7000 and R6400 routers, and maybe other ones too (see list below) were discovered to have a severe vulnerability on Dec 9, 2016.
Netgear responded within 3 days with a new firmware to solve the problem. Good work on their part.
But if you don’t patch and upgrade it is really quite easy to lose to control of your router and grant bad actors total access to your network and router. You will then be subject to a whole list of issues that may be really difficult to clean up.
Here is the CERN posting that details the vulnerability:
