Estado: AplazadaMedia (6.5)—

The The Email Subscribers & Newsletters – Email Marketing, Post Notifications & Newsletter Plugin for WordPress plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.9.27.

This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
