WooMail - WooCommerce Email Customizer <= 3.0.34 - Authenticated (Subscriber+) Missing Authorization to SQL Injection

The WooMail - WooCommerce Email Customizer plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'template_delete_saved' function in all versions up to, and including, 3.0.34. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject SQL into an existing post deletion query.
