Discussion
RoguePlanet is a newly disclosed Windows Defender vulnerability involving a race condition exploit that can spawn a SYSTEM shell if successful. The proof-of-concept (PoC) has been tested on Windows 10 and Windows 11 with June 2026 patches applied, showing variable success rates depending on the machine. Windows Server versions are believed to be vulnerable as well, though the current PoC does not work on them due to user restrictions on mounting ISO images. The exploit targets a race condition in Windows Defender, allowing privilege escalation to SYSTEM level.
