They finally did it. Microsoft has successfully over-engineered a text editor into a threat vector.

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.

As I understood it, there can be specifically crafted links in Markdown documents, which, when clicked, will download a file and then execute it.

RCE means exactly this, the ability to run any code on a remote device (the one running notepad).

It's a parsing issue. I've encountered the same writing an MD parser for a website, not as trivial to solve as it seems. For a multi billion dollar company this is hilariously stupid. Why do I get the feeling someone vibecoded this entire implementation.
