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.

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.
