Phishing is already handled by email. Don't click the zoom meeting link in the email from a Nigerian Prince and you will be fine. In general I don't see this being a problem with Zoom but rather a problem with clicking links from dodgy sources, zoom meeting links just happen to be one of many.
If there are others please list them because I'm struggling to understand the overarching thing you are getting at and examples would help with that.
To answer your question: phishing scams could be one example. I'm sure there are many others.
