This is sort of a convoluted issue, but apparently there is a bug in Chrome, Opera, and Edge Browsers. I've recently been using the Brave Browser, and it wasn't mentioned in the article listed below.

Don't know how much of a concern this is, but one should upgrade to the latest version of the browser you're using, especially if it's one of the three mentioned above.

"The bug (CVE-2020-6519) is found in Chrome, Opera and Edge, on Windows,
Mac and Android – potentially affecting billions of web users,
according to PerimeterX cybersecurity researcher Gal Weizman. Chrome
versions 73 (March 2019) through 83 are affected (84 was released in
July and fixes the issue)."
