LAN command injection via undisclosed input path
Published Jan 13, 2026 · Updated Jan 13, 2026
OS command injection in NETGEAR Orbi mesh devices allows remote authenticated users on the LAN to execute operating-system commands. NETGEAR identifies insufficient validation of attacker-controlled input but has not disclosed the handler, parameter, or unsafe shell operation that reaches the OS. Access requires high privileges and adjacency to the Orbi LAN; the published impact is limited to command execution on the appliance.

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.
