This three-file repository contains a Windows x64 C++ proof-of-concept/operational local privilege-escalation exploit for CVE-2026-69451 affecting the WMI Fastprox component. The main source file, fastprox_eop.cpp, initializes COM security, uses WMI COM interfaces and explicitly defined WMI CLSIDs/IIDs, crafts fake object/vtable and IRecordInfo-related structures, performs heap spraying and pointer-leak/retry logic, and resolves a WinExec-oriented control-flow bridge. It accepts a customizable command and output filename, with additional reliability controls for exploit attempts, object size, and bridge selection. The README provides a whoami /all example, while the GitHub Actions workflow compiles the source with MSVC into fastprox_eop.exe and publishes a Windows x64 release artifact. No remote target, listener, C2 server, or hard-coded network destination is present; exploitation is local and command execution is supplied by the operator.
