What the code does

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

            result = subprocess.run([journal, "--no-pager", "-o", "short-iso", "--since", f"{since_minutes} minutes ago", "-n", str(journal_lines)], capture_output=True, text=True, timeout=12, check=False)

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    elif os.path.exists("/.dockerenv"):

        completed = subprocess.run(full_command, capture_output=True, text=True, timeout=timeout, check=False)

            current = os.path.join(current, part)

    env = dict(os.environ)

SENSITIVE_NAME = re.compile(r"(?i)(^\.env(?:\.|$)|^id_(?:rsa|ed25519|ecdsa)|secret|credential|password|private[_-]?key|^\.npmrc$|^\.pypirc$)")
