Description
The Eventin – Events Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.1.29 via the 'id' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the email address and phone number of any WordPress user, including administrators, by supplying their user id in a query-string parameter while placing the authenticated user's own id in the URL path.
A vulnerability allowing sensitive information exposure has been identified in the Eventin WordPress plugin, specifically in versions through 4.1.29.
