Peplink Security Advisory: Firmware 6.3.5 - OS command injection & Cross-Site Scripting (XSS) vulnerabilities

Thanks for the Security Advisory, — one of the many things that makes Peplink great. I do have a question: From what I understand, there are two definitions for the HW1 designation within the Soho family. I am running a Surf Soho MK 3 with firmware 8.2.1. Is the Mk3 router affected by this Advisory? It appears that I am safe from the other Security Advisory issued today, but perhaps not this one? Thank you in advance for clarification.
