CVE-2026-0404
An insufficient input validation vulnerability in NETGEAR Orbi devices' DHCPv6 functionality allows network adjacent attackers authenticated over WiFi or on LAN to execute OS command injections on the router.
Does this matter?
Lower severity and a low EPSS score (1.06%). Track it; it rarely justifies an emergency change on its own.
