notepad has formatting now? o_O
does it produce markdown or something?
Yep it’s markdown, and yep they had a CVE with second highest grade cause of it
heh, ofc. Apparently something to do with file:// and such uri handling, apparently executing local files? Yikes.
not just local files
if you click a link to file:///123.45.67.89:69420/files-download/virus.exe it will download and run virus.exe
it still works, but now there is a "Dangerous Link Location: This is not a web link and may lead to the execution of malicious code" warning, but previously it would silently run the file.
kinda wild a file-link ever went straight to executing it after download - which on it's own could be dangerous as well.
I guess the "the s in IOT stands for security" also applies to notepad: "the s in vibecoding stands for security"

Neat
Aren't CVE grades meaningless anyway with how they are declared in real world?
We run CVEs through our software inventory and configuration and come up with a new score that measures how bad it is for us.
It's a UWP (i think? they renamed the platform twice already) vibecoded app now, notepad.exe still around.
If you use the formatting bar to format text, it unlocks the View→Markdown menu which has two options - Markdown or Syntax. This allows you to toggle seeing the source or formatted markdown.
If you do not use the formatting bar to format text, markdown is not enabled. I manually typed in text in markdown format and the menu didn't un-grey.
You can go into the app settings and turn off formatting, which will hide the formatting toolbar.
I think you really have to work hard to be offended by this.
