I assume that once/if a method is found it will be applicable broadly though. At the same time, hopefully software patches in V8 and SpiderMonkey will be able to mitigate this further and sooner.

But a JS exploit would require some way to exfiltrate data and presumably doing that would be quite difficult to hide entirely.
