  "title": "Notepad\u002B\u002B: Shortcuts.xml macro HMAC bypass still reachable via the \u0022Run a Macro Multiple Times\u0022 dialog",
  "description": "Notepad\u002B\u002B is a free and open-source source code editor. Prior to 8.9.8, Notepad\u002B\u002B incompletely enforces shortcuts.xml HMAC validation because WM_MACRODLGRUNMACRO, the Run a Macro Multiple Times entry point, calls macroPlayback() without the validation used by command(). A tampered shortcuts.xml macro that is blocked through the Macro menu or a shortcut key can therefore execute through the multi-run dialog and invoke internal Notepad\u002B\u002B commands, including commands that launch external programs, in the current user context. This issue is fixed in version 8.9.8.",
