If you cannot patch yet, restrict peer authentication to trusted parties and consider disabling clipboard sharing if possible.
Description
RustDesk on Windows versions before 1.5.0 does not properly enforce the one-way file transfer setting for peer clipboard file requests. This allows authenticated peers to read files from the host clipboard by sending specific messages that request clipboard file data. The vulnerability has a low severity score and does not impact integrity or availability.
