Security-related question about a possible exposed credential

[Emma-NYL]

Hello,

My name is Emma, I am conducting an academic study on possible credential exposure in public GitHub repositories.

While analyzing this repository, I found a string that may represent a credential. I'm including the code snippet below containing possible leakage. To avoid exposing sensitive information publicly, I marked the sensitive information.

Could you please help clarify whether the detected string is:

1. a real credential, or
2. a placeholder / example value?

Thank you for your time.

Code snippet (sensitive values masked):

                    $userpass = explode(':', $split2[0]);
                    $ftpuser = $userpass[0];
                    $ftppass = (isset($userpass[1])) ? $userpass[1] : '';

                } else {
                    $ftpipport = $split2[0];
                    $ftpuser = 'an****ous';
                    $ftppass = ''repl****pass";
                }

                $ftpipport = preg_split('/:/', $ftpipport, -1, PREG_SPLIT_NO_EMPTY);

                if (checkFtpData($ftpipport[1], (isset($ftpipport[1])) ? isset($ftpipport[1]) : 21, $ftpuser, $ftppass) === true) {

Thank you in advance for your time - I really appreciate it!

Sincerely,
Emma
