As a follow-up, I did get this message from my IT support.
Thank you for your message. Zoom has released a patch in response to this security concern, so we recommend that you update to the latest client on your machine. You may check for updates by opening your Zoom app window clicking zoom.us in the top left corner of your screen and then clicking Check for Updates, or you may choose to download the latest version directly from zoom.us/download.
Zoom also released a statement in response to user concerns saying, “To be clear, the host or any other participant cannot override a user’s video and audio settings to, for example, turn their camera on.”
