CVE-2026-9214

Administrator router tampering via insufficient input validation

Published Aug 11, 2026 · Updated Aug 11, 2026

Improper input validation in NETGEAR R7000 firmware 1.0.12.216 allows remote authenticated users to modify router software and functionality. NETGEAR has not disclosed the affected interface, parameter, or validation operation, so the precise input-handling mechanism is unavailable. Exploitation requires an administrator account and access from the router's local network; the reported consequence is unauthorized integrity modification, not data disclosure or service interruption.
