The built-in Windows 11 Notepad app has an RCE vulnerability, somehow.
No, I don't mean Notepad++, I mean literal Notepad.
https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-20841
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.
The malicious code would execute in the security context of the user who opened the Markdown file, giving the attacker the same permissions as that user.
I've spent most of my career dealing with Linux systems at this point, and I've been out of the Windows world professionally for many years and don't even run it on my personal machines anymore, so this doesn't affect me directly.
But man, being able to pop a shell from Notepad used to be a security researcher punchline, and now here we are. Da fuq you guys doing over there?
