== Sensitive Code Example

----
// Any reference to STDIN is Sensitive
$varstdin = STDIN; // Sensitive
stream_get_line(STDIN, 40); // Sensitive
stream_copy_to_stream(STDIN, STDOUT); // Sensitive
// ...


// Except those references as they can't create an injection vulnerability.
ftruncate(STDIN, 5); // OK
ftell(STDIN); // OK
feof(STDIN); // OK
fseek(STDIN, 5); // OK
fclose(STDIN); // OK


// STDIN can also be referenced like this
$mystdin = 'php://stdin'; // Sensitive

file_get_contents('php://stdin'); // Sensitive
readfile('php://stdin'); // Sensitive

$input = fopen('php://stdin', 'r'); // Sensitive
fclose($input); // OK
