In July of 2019 the public was made aware of a security vulnerability in the popular video conferencing app, Zoom (used by MSU) on Macs. If the Zoom app is installed on a Mac, then any website can open a video-enabled call since the Zoom app installs a web server on Macs that accept requests other browsers wouldn't. Even if you uninstall the app, the web server still exists and can reinstall Zoom without your knowledge.
To avoid unwanted and unknown websites from accessing your camera, it is recommended that you keep your Mac operating system up-to-date. More information regarding this flaw and other steps you can take to safe guard your privacy can be found in the article "Serious Zoom security flaw could let websites hijack Mac cameras" from The Verge.
