  "description": "Notepad\u002B\u002B is a free and open-source source code editor. Prior to 8.9.7, the Notepad\u002B\u002B Windows 11 x64 and ARM64 installer passes the attacker-influenced installation directory \u0060$INSTDIR\u0060 from PowerEditor/installer/nppSetup.nsi into a PowerShell \u0060-Command\u0060 string used by RegisterMSIX to invoke Add-AppxPackage, allowing PowerShell subexpression syntax such as \u0060$()\u0060 in the installation path to execute commands in the installer\u0027s security context when the context menu component is selected. This issue is fixed in version 8.9.7.",
