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):

roomRouter.get('/info/:id', async (req, res) => {
  const roomId = req.params.id;
  let dbRoom = await ClaRoom.findOne({ id: roomId });

  if (dbRoom) {
    dbRoom.attendeePassword = '*****';
    dbRoom.speakerPassword = '*****';
    res.status(200).send(dbRoom);
  } else {
    res.status(404).send(`room ${roomId} do not existed!`);
  }
});

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

Sincerely,
Emma
