Description
The Events Made Easy plugin for WordPress is vulnerable to shortcode injection via the frontend event submission form in all versions up to, and including, 3.3.6, due to the plugin storing guest-supplied event fields, attributes and properties (such as the event notes, the single event format and custom event attributes) without neutralizing shortcode and placeholder syntax, while the event placeholder replacement runs do_shortcode() on the result when the event is displayed. This makes it possible for unauthenticated attackers, when guest event submission is enabled, to execute arbitrary shortcodes and placeholders in the context of the site.
