This is why software updates and long term support is important. This situation will blow over as well - be glad that advisories were issued and people have time to patch it before it gets exploited. Back in the 70s-90s, it'll be viral and entire infrastructures and systems go down instead. This is just one that happens to make the news, but it must be stated: many vulnerabilities hit for many products. It's quite impossible to catch them all.
In the nature of software development, bugs are bound to take place. When products span millions of lines of code across tens or hundreds or even thousands of people, it's inevitable that something will go wrong. And when someone fixes something, they could very well break something else. Again that's expected behaviour in any software product.
I hope you can see why having a company's supporting their products for a reasonable time, and providing timely software updates for a reasonably long amount of time (expected lifespan for networking equipment is about 5y, and can be counted on to last 10y in some installations), is very important. You'll probably recall I called out TP-Link's Omada for absolutely horrible software support that disappeared after about 14 months for my old EAP245, after they released a new hardware version they completely ignored their older hardware. Instead, be glad that we will see that Ubiquiti will be working to patch this vulnerability and issue updates to even their their older affected products.
