Unwanted physical access to a computer by a malicious individual IS a concern, however, embedding a malicious terminal command inside a stack does NOT require physical access to the computer (of course). Emphasis mine on the 'of course'. Windows and Linux will let it through unchallenged. (Yes, newer versions of MacOS will prompt to allow LCC/OXT use of the terminal commands) - but in the real world, with mixed operating systems on the network - if you want to run malicious terminal code - you'd just use a stack designed to run the malicious part on Windows or Linux (or an older version of MacOS)... no physical access to the computer required.
