I have 2 WYZE cameras currently that are older v2's using a common WiFi base for connectivity, 2 WYZE Cam OG's and two more OG's being delivered today. According to the WYZE website these devices are not affected and my current firmware is the latest. Well, enuff of that yadda yadda, smart people isolate iOT devices as I also have. Fortunately, I have an iOT network built into my TP-Link router that does that isolation. In a nutshell, if you have ANY WYZE devices isolate them immediately regardless. The company has not had a stellar record for keeping firmware updates a priority so its seriously recommended.
