This CVE is an 8.8 severity RCE in Notepad of all things.
Apparently, the “innovation” of adding markdown support came with the ability of launching unverified protocols that load and execute remote files.
We have reached a point where the simple act of opening a .md file in a native utility can compromise your system.
That’s the opposite of how I would understand it though. If you said a passive RCE I would understand that as it being run without me doing anything - in this case, just having notepad open making me vulnerable.
