Federal Civilian Executive Branch agencies need to patch Sitecore instances by September 2025 to avoid being hit by CVE-2025-53690. This flaw lets cyber baddies use ASP.NET machine keys to execute remote code. It’s like leaving your front door key in a public guidebook—just waiting for the wrong party to RSVP.
Hot Take:
