To ensure that sensitive vulnerability data is only accessible by registered and authorized users

Context

Description

defmodule UserManager do
  def assign_treatment_manager(email, vulnerability_id) do
    send_vulnerability_email(email, vulnerability_id)
  end

  defp send_vulnerability_email(email, vulnerability_id) do
    # Email sending logic here
end...

In this code, the function `assign_treatment_manager` allows any email address to be assigned as a manager of vulnerabilities. This means the system could potentially send sensitive vulnerability data to non-registered users, or users who no longer have access to the system.

defmodule UserManager do
  def assign_treatment_manager(email, vulnerability_id) do
    if is_registered_and_authorized?(email) do
      send_vulnerability_email(email, vulnerability_id)
    end
  end

    # Email sending logic here...

In the secure version of the code, the system checks whether the user is registered and still part of the organization before assigning them as a treatment manager. Also, when a user is removed from all projects, their access is effectively revoked.
