CVE-2026-11739

Device compromise via command injection during traffic interception

Published Aug 11, 2026 · Updated Aug 11, 2026

Command injection in NETGEAR Nighthawk firmware before model-specific fixed versions allows attackers to compromise affected devices. NETGEAR has not disclosed the affected function, command-construction path, untrusted traffic field, or management workflow that invokes the command interpreter. Exploitation requires attacker-in-the-middle control of local network traffic and affects device confidentiality and integrity, with no reported availability impact.
