 "title": "Event Manager and Tickets Selling Plugin for WooCommerce <= 5.7.10 - Unauthenticated Arbitrary Shortcode Execution via Event Calendar Filter",
 "description": "The Event Booking Manager for WooCommerce plugin for WordPress is vulnerable to arbitrary shortcode execution via the mep_gat_event_calender AJAX action in all versions up to, and including, 5.7.10, due to user-supplied calendar filter values (cat, org, tag, city, country, status and year) being concatenated into a [mep-event-calendar] shortcode string that is passed to do_shortcode(). esc_attr() does not remove square brackets, and the only nonce the action checks is printed to every visitor on the plugin's front-end pages. This makes it possible for unauthenticated attackers to close the shortcode tag early and execute arbitrary shortcodes registered on the site.",
