High (7.3). EPSS 0.6% chance of exploitation in the next 30 days.
The The Authors List plugin for WordPress is vulnerable to arbitrary shortcode execution via update_authors_list_ajax AJAX action in all versions up to, and including, 2.0.4. 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.
