Title
YayMail <= 4.3.2 - Missing Authorization to Authenticated (Shop Manager+) License Key Deletion via '/yaymail-license/v1/license/delete' Endpoint
Summary
The YayMail – WooCommerce Email Customizer plugin for WordPress is vulnerable to unauthorized license key deletion due to a missing authorization check on the `/yaymail-license/v1/license/delete` REST endpoint in versions up to, and including, 4.3.2.
