A micropatch is now available for a zero-day vulnerability in Windows that allows unauthorized read access with the highest privileges to any file on the operating system. The temporary fix is for the third security bug released publicly by security researcher SandboxEscaper. An official patch from Microsoft is currently unavailable, although exploit code was published a month ago on GitHub, now a Microsoft-owned resource. The fix is free and works for the fully updated 64-bit Windows 10 version 1803 and Windows 7.
