LegacyHive Is a Local Privilege Escalation BugThe vulnerability hunter in a feud with Microsoft released yet another Windows zero-day Tuesday as promised, though the touted "bone-shattering" disclosure was stripped down to prevent public exploitation. LegacyHive, exploits a profile-loading race condition to access another user's registry hive.

LegacyHive PoC exposes a Windows Privilege Escalation flaw affecting fully patched Windows desktop and server systems. Just hours after Microsoft’s July 2026 Patch Tuesday, security researcher Nightmare Eclipse, also known as Chaotic Eclipse, published a new Windows zero-day proof-of-concept called LegacyHive. This time, the target is the Windows User Profile Service (ProfSvc), and unlike the […]
