MiniPlasma Zero-Day: PoC Exploit Code and Vulnerability Details Publicly Disclosed for Windows 11

A researcher published “MiniPlasma,” a public proof-of-concept exploit that resurrects a six-year-old elevation-of-privilege flaw in the Windows Cloud Files Mini Filter Driver (CVE-2020-17103), allowing reliable race-condition-based escalation to a SYSTEM shell on fully patched Windows 11 and Windows Server 2025; the author has a history of releasing unpatched zero-days and the PoC reportedly succeeds consistently against current Windows releases, presenting immediate exploitation risk.
