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.

An attacker could trick a user into clicking a malicious link inside a Markdown file opened in Notepad

So you can give someone a Markdown file with a link to an application, and if they click the link the application runs.

Markdown supports links, yeah.

But Notepad doesn't, so it shouldn't render .md files, it should just show the markdown code.

They keep adding stuff to notepad that no one was asking for. Like tabs and saving on exit, which breaks the workflow of having notepad be a throwaway scratch pad.

Notepad saves on exit now? Wtf.

Have been for a while now. In neat (read: horrible) little tabs that never go away unless you manually force them to.
