YI Home Camera 2 CVE-2026-4475

No vendor-released patch identified at time of analysis - Yi Technology did not respond to responsible disclosure attempts. Primary mitigation is network segmentation: isolate YI Home Camera 2 devices on a dedicated VLAN or IoT network segment with strict firewall rules preventing lateral movement to trusted networks. Block all inbound access to camera web interface (typically TCP ports 80/443/8080) from untrusted network zones using ACLs or firewall policies. If camera must be accessible remotely, implement VPN-only access rather than direct exposure, and enforce strong authentication at the VPN gateway. For high-security environments, consider replacing affected devices with alternatives from vendors with active security response programs. Compensating controls trade-offs: Network isolation is highly effective but requires managed network infrastructure (may not be feasible for home users with consumer routers). Disabling web interface if camera supports mobile-app-only operation reduces attack surface but limits management flexibility. Continuous monitoring for unauthorized access via camera logs or network IDS signatures for /home/web/ipc access patterns can provide detection, though alert fatigue risk is moderate. Users unable to implement network controls should disconnect affected cameras from networks containing sensitive systems or data.
