Advisory

Source description from Wordfence Intelligence, credited to 0xd4rk5id3.

The The Cozy Blocks – All-in-One Page Builder Blocks for Gutenberg and Full Site Editing (FSE) plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.1.29. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
