Config::IniFiles::_make_filehandle opens a filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe (\"| cmd\", \"cmd |\") or begins with a redirect (\"> path\", \">> path\") is run as a command or redirect rather than opened as a file. The helper is the open path behind the documented -file argument: new(-file => $thing) reaches it through ReadConfig. An in-memory scalar reference (-file => \\$text) does not open a path and is unaffected.  Any caller that forwards untrusted input to the -file argument can run an arbitrary command or truncate a file under the process UID.",
