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):

  // redis 配置，默认是本地
  redis_host: '127.0.0.1',
  redis_port: 6379,
  redis_db: 0,
  redis_password: '',

  session_secret: 'node_c****secret', // 务必修改
  auth_cookie_name: 'node_club',

  // 程序运行的端口
  port: 3000,

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

Sincerely,
Emma
