CVE-2026-48778

Description

Notepad++ is a free and open-source source code editor. Prior to 8.9.6.1, the <GUIConfig name="commandLineInterpreter"> tag in config.xml is read by NppXml::value() (Parameters.cpp:6430) and stored in _nppGUI._commandLineInterpreter without any validation, whitelist, or digital signature check. When the user triggers IDM_FILE_OPEN_CMD (File → Open Containing Folder → cmd), NppCommands.cpp:228 creates a Command object with this value and calls run(), which invokes ShellExecute (RunDlg.cpp:221) with the attacker-controlled string as the executable path. This vulnerability is fixed in 8.9.6.1.
