Code Snippet

The following code snippet highlights the potentially impacted lines within the /api/public/signup file:

app.post('/api/public/signup', async (req, res) => {
  try {
    const {email, password} = req.body;

    const newUser = new User({
      email,
      password : await User.encryptPassword(password),
    });

    const savedUser = await newUser.save();
    res.status(200).send({status: 'User saved successfully'});
  } catch (error) {
    res.status(500).send({error : "Server error"});
  }
});

This code fragment manages the user registration process by creating new user accounts through the Signup API. It is imperative to note the potential for exploitation within the API, specifically concerning the access controls.
