Microsoft has fixed a remote code execution vulnerability in Windows 11 Notepad that allowed attackers to execute local or remote programs by tricking users into clicking specially crafted Markdown links, without displaying any Windows security warnings. Markdown support means Notepad can open, edit, and save Markdown files (.md), which are plain text files that use simple symbols to format text and represent lists or links. 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.
