The Envos Elementor Templates & Widgets for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.4.4. This is due to missing or incorrect nonce validation on the ajax_theme_activation function. This makes it possible for unauthenticated attackers to activate arbitrary installed themes via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
