Description
The Events Made Easy plugin for WordPress is vulnerable to Insecure Direct Object Reference via the front-end task signup form (eme_tasks AJAX action) in all versions up to, and including, 3.3.2, due to missing validation that the submitted task IDs exist and belong to the event they are submitted under. This makes it possible for unauthenticated attackers to sign up for tasks of other events while the checks of a more permissive event are applied, bypassing the target event's registered-users-only, approval, one-signup-per-person and open-spaces restrictions, and to store signups linked to the wrong event.
