A critical flaw has been discovered in Notepad (CVE-2026-20841). That once simple Windows editor that only displayed plain text, you know? The one that Microsoft tainted with Markdown (the vector for this flaw), Copilot, and who knows what else? An attacker could place a malicious link in a Markdown file that, when clicked by the victim, would execute code remotely. A fix was made available by Microsoft in routine updates released on Tuesday (10^th).
