What is CVE-2019-13450?
CVE-2019-13450 is a medium-severity missing authorization vulnerability in Zoom Zoom, published on 9 Jul 2019. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
In the Zoom Client through 4.4.4 and RingCentral 7.0.136380.0312 on macOS, remote attackers can force a user to join a video call with the video camera active. This occurs because any web site can interact with the Zoom web server on localhost port 19421 or 19424.

Blocking exploitation requires additional steps, such as the ZDisableVideo preference and/or killing the web server, deleting the ~/.zoomus directory, and creating a ~/.zoomus plain file.
