Adjacent command injection via DHCPv6 input validation
Published Jan 13, 2026 · Updated Jan 13, 2026
OS command injection in NETGEAR Orbi firmware before 7.2.8.5 allows attackers on the adjacent network to execute router commands via DHCPv6. NETGEAR identifies insufficient validation in DHCPv6 functionality but has not published the affected handler, input field, or command-building operation. Reachability requires WiFi authentication or LAN access and enabled DHCPv6, which is disabled by default; successful exploitation runs commands on the router.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
