What is CVE-2023-0766?

The Newsletter Popup WordPress plugin, up to version 1.2, lacks crucial CSRF checks, enabling attackers to exploit the wp_newsletter_show_localrecord page. This oversight allows unauthorized actions by logged-in users, posing a significant security risk. Without proper nonce protection, the plugin's inability to validate requests makes it vulnerable to CSRF attacks, potentially compromising user accounts and data integrity.
