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

The Web-based Management allows a remote low privileged Engineer user to install additional APPs on the device downloaded from the PLCnext Store without implementing any data verification mechanism, leading to the capability for an Engineer user to reach arbitrary code execution with root privileges on the PLC device. A successful exploitation may allow to install a manipulated APP package, potentially impacting integrity and availability of the PLCnext Control.
