Vulnerability in input-leap Input Leap

[ Description ]Official description

Input Leap (aka input-leap) through 3.0.3, when the non-default --enable-drag-drop option is used on Windows or macOS, mishandles the / versus \ distinction and allows directory traversal, with resultant code execution if a file is written to a startup directory. This occurs via a DDRG message.
