The article’s actual title is: Zoom Zero Day: 4+ Million Webcams & maybe an RCE? Just get them to visit your website!
But, assuming I’m reading it correctly, the “maybe an RCE?” part seems like fear-mongering, because it would require that Zoom lose control of one of the domains that they trust for transparent client installs/upgrades.
I’m also a little concerned about how some parts of the article don’t match up. For example, the “UPDATE: June 7th, 2019:” does not have (as far as I can see) a matching entry in the Timeline. There is an entry for July 7, noting a regression; but there is an update the next day (July 8) noting that the regression has been fixed.
