Dang kids. Because of an optional parental-control feature that apparently wasn’t so optional, nearly a dozen widely used Netgear home Wi-Fi router models have a serious security flaw and need to be patched.

The affected models are the R6400v2, R6700, R6700v3, R6900, R6900P, R7000, R7000P, R7850, R7900, R8000 and RS400, most of them in the “Nighthawk” line and physically nearly identical. Firmware updates are now available for all of them.
