Microsoft Actively Patching 'RoguePlanet' Zero-Day Vulnerability in Windows Defender
Microsoft issued a security advisory on Wednesday acknowledging a privilege escalation vulnerability (CVE-2026-50656, CVSS 7.8) in its Windows Defender product. The zero-day flaw was publicly disclosed last week by security researcher Nightmare Eclipse (also known as Chaotic Eclipse) before a patch was available. Microsoft says it is developing a high-quality security update and will provide details once the fix is complete.
