No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

luci-app-openvpn fails to properly validate the instance_name2 parameter during file upload, allowing authenticated users to perform path traversal and write arbitrary files outside the intended directory. Attackers can upload malicious payloads to gain persistent root code execution by placing SSH keys in system directories accessible on reboot.
