The risk is significantly reduced when PCM600 is configured with High Security Level, as unsigned project files cannot be imported. As a result, attackers cannot rely on users importing manipulated unsigned archives. Organizations that restrict project imports to trusted sources and enforce High Security Level settings substantially reduce exposure to this vulnerability. Refer to section “General security recommendations” for further advise on how to keep your system secure.
