CVE-2026-19586

A pre-authentication OS command injection vulnerability has been identified in Omada gateways configured to operate as an OpenVPN Server due to insufficient validation of client-supplied data during OpenVPN connection establishment. An unauthenticated remote attacker may provide specially crafted input influencing backend command execution logic before authentication completes. Exploitation requires the OpenVPN Server feature to be enabled, VPN service reachable by the attacker and attacker to be able to initiate an OpenVPN connection attempt.  Successful exploitation may allow arbitrary command execution, potentially leading to full compromise of the affected device.
