Code Examples​

Compliant code​

The server side of the application performs credential validation for each user

const changePassword = (req, res) => {
  if (isValidUser(req.body.user) && isValidCredentials(req.body.userSession)) {
    const newPassword = req.body.newPassword;
    changeUserPassword(req.body.userId, newPassword);
  }
}

Non compliant code​

The server side of the application does not validate user permissions before changing passwords

const changePassword = (req, res) => {
  if (isValidUser(req.body.user)) {
    const newPassword = req.body.newPassword;
    changeUserPassword(req.body.userId, newPassword);
  }
}
