Guest users can subscribe to a newsletter even if the module is disabled from the Magento admin panel

[pullemall]

Preconditions and environment

• Magento version 2.4.6

Steps to reproduce

1. Disable the newsletter module in the Magento admin panel
2. Send the AJAX POST request to the controller newsletter/subscriber/new with necessary data e.g.: email: test@test.test
3. Check newsletter subscribers

Expected result

When the module is disabled a guest user is unable to subscribe to newsletters

Actual result

When the module is disabled a guest user can subscribe to newsletters

Additional information

The issue happens because the controller's method \Magento\Newsletter\Controller\Subscriber\NewAction::execute doesn't check if the module is enabled or disabled, but the default config allows guests to subscribe to newsletters:

Hi @@engcom-Bravo
Thanks for your reply.
You don't need to disable the module itself on the server, only turn it off from the Magento admin panel. Sorry for the ambiguity.
