Description
The Eventin – Events Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure via event organizer/speaker assignment and the etn_speaker_events and etn_organizer_events shortcodes in all versions up to, and including, 4.1.26. This is due to the plugin accepting any user ID as an event organizer or speaker, and rendering a speaker/organizer profile for any user ID given in the shortcode 'id' attribute, without checking that the user is a speaker or organizer. This makes it possible for authenticated attackers, with Contributor-level access and above, to show the email address and phone number of arbitrary users, including administrators.
