"An attacker could trick a user into clicking a malicious link inside a Markdown file opened in Notepad, causing the application to launch unverified protocols that load and execute remote files."
I didn't even know Notepad would render Markdown.
Torture will continue until morale improves
I think it's very recent, I use it almost daily and only last week did I see a markdown file being rendered.
Notepad rendering other formats removes one of the specific reasons I use notepad: to strip the stupid formatting that all sorts of applications seem to want to attach to text these days.
Notepad handily strips away all the custom link namings and formats that totally fuck the expected output of a simple copy and paste. That's a big part of the its magic: it's immunity to the choices of marketing teams and dud management.
