Prior to 8.9.6.1, the <Command> tag text content inside <UserDefinedCommands> in shortcuts.xml is read by NppXml::value(aNode) (Parameters.cpp:3658) in the feedUserCmds() function and stored in UserCommand._cmd without any validation. When the user clicks the corresponding entry in the Run menu, NppCommands.cpp:4264 creates a Command object with string2wstring(ucmd.getCmd()) and calls run(), which invokes ShellExecute (RunDlg.cpp:221) with the attacker-controlled string as the executable path. The injected command appears as a normal menu item in the Run menu, making it a viable persistence mechanism.  This vulnerability is fixed in 8.9.6.1."
