The 2-arg form interprets magic prefixes: \u0027| cmd\u0027 and \u0027cmd |\u0027 open a pipe to a subprocess, \u0027\u003E path\u0027 and \u0027\u003E\u003E path\u0027 open the path for write or append.\nUntrusted input passed to send_file() can run OS commands at the daemon process UID. The read-pipe form (\u0027cmd |\u0027) also leaks subprocess stdout into the HTTP response body. The write-mode forms can create or truncate files at attacker chosen paths.",
