Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in WPChill RSVP and Event Management Plugin allows SQL Injection. This issue affects RSVP and Event Management Plugin: from n/a through 2.7.14.

The RSVP and Event Management plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on several AJAX functions like bulk_delete_attendees() and bulk_delete_questions() in all versions up to, and including, 2.7.13. This makes it possible for unauthenticated attackers to delete questions and attendees and for authenticated users to update question menu orders.

The RSVP and Event Management Plugin WordPress plugin before 2.7.8 does not have any authorisation checks when exporting its entries, and has the export function hooked to the init action. As a result, unauthenticated attackers could call it and retrieve PII such as first name, last name and email address of user registered for events
